A subjective halfway view

I’ve just acted as subject in our first investigation into the memorability and impact of information nuggets. The nugget material, in this case, was mindmaps of key points in nineteen esoteric-type books which explore perceived unresolved mysteries from ancient Egyptology to modern secret societies.  I discovered that I could remember almost none of the points presented to me and was unable to link any of them to a particular development in my thinking. My immediate reaction to this disappointing – but probably to be expected – finding was that these are not actually nuggets of information but instead are just parts of a summary of each book.

However, on reflection, I’ve reversed that view. After all, when I was picking out the points as I read, I must have thought each of them to be significant – otherwise I wouldn’t have picked them out. So, how is a key point in a book different from a key point in, say, a five page article? Well there are some obvious differences like the book is a lot bigger and has a lot more stuff in it – most of which I’m not familiar with AT ALL. Unless one has a photographic or otherwise superb memory, you wouldn’t expect to remember everything in such a book after one quick casual read. Of course, I have the books on my bookshelf and have the look of each one locked in my memory with some ideas of what it’s about. However, this is the case because there are just a few hundred of them, and they have a rich content and the covers and spine usually have distinctively memorable images. In contrast, the articles and documents in my work collection (which are due to be investigated next), are much more numerous; are hidden away in my computer (with just a few in my physical archive box); and they all look very similar and have very few distinctive markings.

I guess I’ve expanded my thinking this morning about all this. However, I’m only the subject and we’re only half way through the overall exercise. The interesting bit will be what the researcher concludes from it all.

The truth about truth

Maybe most people have already twigged this, but the BBC programme ‘The Capture’ has made me realise that we can no longer rely on videos for the truth. It illustrates how live camera feeds can be altered – dramatically. I believe sophisticated and moneyed organisations can do this today; and I think it will become easier as time goes by.
So, to add to the possibility of text being untrue, and of people’s accounts and memories being untrue, and of photos being faked, we must add that videos may be false. Is there anything left – well perhaps just our own internal thoughts and memories, but no doubt our race will get to manipulating those too.
So, I guess, we are back to a great truth that our enquirers and thinkers have known for hundreds of years: there is no substitute for diligence and multiplicity in our search for what is and what has been. Our modern technology has made us slack and gullible and persuaded us that we can nail down reality. In fact, reality has to be carefully investigated and checked and rechecked, and then still considered with a critical eye as we use it generously to develop our understanding and knowledge.

Power Booking

People in power a few hundred years ago just didn’t have access to up to date global information. These days such people have no excuse as  large numbers of diligent writers research global issues and publish up to the minute resumes on a wide range of topics around the world. There is no excuse for failing to be aware of what humans have done, and continue to do, to each other; what effects we are having on the planet we live and depend upon; what our universe might consist of; and what possible futures we might have within it. Even I, with just a few books I have read in the last few years, feel informed and broadened. If each world leader were to be given just ten or fifteen books to read at the start of their reigns, perhaps they would act rather more in the interests of all of us, than they currently appear to do so.

PAWDOC: Requirements and Objectives

The 2001 paper reviewing the first 20 years of use of the PAWDOC system listed 23 requirements for a Personal Electronic Filing System and provided a status for each one.  The table below reproduces that listing and also provides an updated status for PAWDOC in 2019.

Requirement 2001 Status 2019 Status Notes
Requirements dictated by The Job
1. Cope with large amounts of material, some of which becomes redundant very quickly. Fully met Fully met
Requirements dictated by the physical environment in which the system is used
2.Cope with changing terminology Not met at all Not met at all This would require specific functionality in the Index.
3. Be capable of being operated in temporary and limited office accommodation. Partially met Fully met Not fully met because the whole collection is now digitised on the laptop; and scanners are found in most offices.
4. Be easily portable. Partially met Fully met Now fully met because laptops are now small and powerful, and have more than enough storage.
Requirements to support the information sources used

7. Record references to material in other people’s filing systems. Fully met Fully met
8. Manage information received via email and computer conferencing systems (including Lotus Notes). Partially met Fully met Now fully met because any file formats can be handled, and getting email content into such files is not the concern of the filing system.
9. Record references to material in remote systems such as Lotus Notes databases and web sites, and access those remote systems and retrieve the relevant information. Partially met Fully met HTML references are included in Filemaker Index entries, and can be opened by selecting them and right clicking which presents an ‘Open’ menu option.

21. Assist the user to identify knowledge developments that are occurring and to choose what areas to focus on. Not met at all Not met at all This would require special functionality in the filing system.
Technology support
22. The technology must be cheap enough for an organization not to quibble over, and for individuals to buy for themselves. Partially met

23. The technology must be reliable enough not to require expensive maintenance contracts or multiple one-off repairs. Partially met

 

Fully met

 

This is now fully met because the technology required is standard and now very reliable.

Two things are clear from the comparison of the status in 2001 and 2019: the technology for a personal electronic filing system has now become commonplace and relatively cheap; and, no developments have occurred to support the particular requirements of ‘coping with information and communication overload’, and of ‘supporting knowledge acquisition and development’. I believe the latter is probably true not just for the PAWDOC system but generally – I have not heard of any work going on in these areas.

The 2001 paper also described three objectives for the work:

  • To provide practical feedback to product developers, system designers, and other (potential) users regarding the real day-to-day requirements of individuals using personal electronic filing systems.
  • To establish an office document test set.
  • My own personal need to stay organised and efficient in my day-to-day work.

Of the three, only the final one – to keep myself organised – has been fully achieved.

Regarding the first objective, I have done my best to document my experiences and make that information freely available to product developers, system designers and other users, but I have seen no evidence to suggest much interest – it seems there is not a consumer-led demand for this capability. Certainly, I have come across very few people, if any, who have been operating an all-inclusive PAWDOC-type system without any direct contact with myself.

I believe the second objective – to establish on office document test set – has simply been overtaken by events; the huge strides made in search & retrieval algorithms by internet search engines such as Google over the last 30 years has simply removed the need for such test sets.

Over the last 15 years or so, two more potential objectives – or at least potential uses – have come to mind: first, as huge changes continue to occur as a result of ever-increasing computing power, the universality of the mobile phone, and the ubiquity of the internet, it has occurred to me that the PAWDOC collection provides a unique insight to the early stages of this massive transition in business and society in general. Therefore, I continue to seek a permanent repository for the collection, in the belief that it may hold some value for future researchers.

The second additional objective concerns digital preservation. In order to ensure PAWDOC’s future accessibility, I have had to develop suitable digital preservation processes and documentation and to apply them to the very diverse range of material in the collection. In the course of this work it has occurred to me that the collection might be useful to the digital preservation community as a test bed and training tool. If I have no success in finding a permanent destination for the collection as a research tool, I may then try to find a home for it within the digital preservation community.

This entry brings to an end my own personal final review of the PAWDOC personal electronic filing system. The remaining work to be done is to assemble a set of Conclusions. However, this will be a joint effort between Peter Tolmie, an independent researcher, and myself.

PAWDOC: Architecture

Four types of prototype solutions have been used in the course of this work: card index, electronic index, electronic index and document management system, and electronic Index and file storage in Windows 10 folders. The timeline of development is shown below and the architecture of each solution is described in the subsequent text.

1980      Visit to Amoco Research Centre, Tulsa: first electronic office filing system seen
1981      First entry placed in card index (1 June 1981
1987      Implementation of a computer-based index – Filemaker software on a Macintosh
1993      Movement of Filemaker index from Macintosh to a Compaq LTE Elite laptop running MS Windows
1994      Scanner and Magneto-Optical drive loaned by Fujitsu
1995      Paperclip Document Management software loaned by DDS
2000      Paperclip upgraded to FISH product and loaned by Ringwood Software (which was subsequently taken over by Azur Group, which was taken over by Maxima which was taken over by m-Hance)
2018      FISH document management system removed and replaced with Windows 10 folders

1. Architecture of the card index system, 01Jun1981 – 30Dec1987

 This consisted of paper documents stored in an upright cabinet in serial number order, and an index on 6×4 inch cards. The cards were initially held in a small plastic box with a lid, and later on in a metal drawer. The index consisted of a series of title cards with an entry for each document (serial number, title, keywords) and a set of keyword cards – each one having a keyword on the top and then all the entries possessing that keyword listed underneath. The rationale for this filing schema was worked out with my colleague John Pritchard, and it continues to form the basis for the system as it stands today. The Card Index Architecture is illustrated below.

2. Architecture of the electronic index, Jan1988 – Dec1994

After being provided with a Macintosh computer at work, I selected Filemaker, a general purpose database with great flexibility and ease of use, to hold the Index. The fields used for the Filemaker index are:

  • Reference number.
  • Title/keywords.
  • Movement status (to record the location of items borrowed by people, archived, lost, etc.).
  • Publication date (to indicate when an individual item was first published).
  • Creation date (to record when an item was catalogued into the filing system).
  • Date last accessed (to record when an item has last been retrieved thereby enabling items that have never been accessed, or least recently accessed, to be identified as most suitable for archiving).

By 1988, the amount of paper had overflowed the upright filing cabinet and I had started to archive less frequently accessed documents to cardboard liquor boxes, which were stored around me in my office. The architecture of the Electronic Index system is illustrated below.

3. Architecture of the electronic index and document management system, Jan1995 – Feb2018

In 1994 Fujitsu offered to support the work by providing, on long-term loan, a scanner and a magneto-optical storage system; and in 1995 DDS, the European distributors of the PaperClip document management system, provided PaperClip on a long-term loan basis. By the beginning of 1996, these components had all been trialled and tested and were operational. Paperclip provides drawers, folders within drawers, and documents within folders. All the PAWDOC folders were contained in a single drawer; and a single folder was allocated to each PAWDOC Reference Number. Multiple documents of one or many formats could be contained within a folder.

Paperclip interworked with Filemaker by control key combinations which, when selected within Filemaker, copied specified information on the screen, imported it into Paperclip and enacted a Paperclip action. Two interworking functions were set up:

  • Search (search for a folder in Paperclip based on a reference number picked up in Filemaker);
  • Create (create a new folder in Paperclip and insert the Filemaker reference number into the folder index field).

PaperClip was upgraded to FISH in 2000. The architecture of the combined Index and document management system is illustrated below.

4. Architecture of the electronic index and Windows 10 folders, Mar2018 – present

The companies that owned the European rights to the Fish document management system were successively taken over in the first 15 years of the new millennia, and, by 2017, Fish was owned and supported by m-Hance. However, the digital preservation exercise undertaken on the PAWDOC collection in 2017 learned that there were no plans to develop Fish any further, so it was decided to remove Fish and replace it with Windows 10 folders. The conversion was undertaken successfully in 2018. The Electronic Index and Windows 10 Folders architecture is illustrated below.

PAWDOC: Costs and benefits

Operating a Personal Electronic Filing System is no trivial matter – it takes determination and an appreciable amount of extra time. So, is it worth it? The answer depends very much on the type of person you are. Those who like to be organised will find it helps them to be even more organised, as well as keeping their documentation in order and enabling them to find things when they need them. There is the added benefit of it gradually building a complete collection over a period of time, which can be referred back to at will. Those who are inclined to operate with a little less order may be disinclined to spend their time on what can be perceived as a purely administrative activity.

The costs involved are relatively low. Laptop, scanner and storage technologies are now all sufficiently well developed as to be more than able to support a Personal Electronic Filing System. The additional cost of the PAWDOC system, over and above the laptop and its operating system, is around £900.

Specific questions relating to this aspect are answered below. Note that the status of each answer will fall into one of the following 5 categories: Not Started, Ideas Formed, Experience Gained, Partially Answered, Fully Answered.

Q58. How much does a personal electronic filing system cost?

2001 Answer: Experience gained: The costs are falling. Approximate 2001 prices of the components are:

  • Filemaker Pro £220
  • FISH Document Management System and Sybase SQL Anywhere single user combination £2095 (a 10-user networked version of FISH costs about £10 000)
  • Fujitsu Scanpartner 10 Sheetfeed and Flatbed Scanner £821
  • Fujitsu MO Drive (currently 1.3 GB) £388
  • CD Writer hardware £82
  • Adobe CD Creator (often bundled with CD writers) £45

Total price (excluding the laptop PC) for the configuration used in this study is £3650. However lower priced solutions with broadly similar capabilities can certainly be assembled from alternative products (for a list of low cost Personal Knowledge Management Tools see http://www.destinationcrm.com/articles_-images/km/pkmtchart.htm)

2019 Answer: Fully answered: After removing the document management system from the PAWDOC architecture in 2018 and replacing it with Windows 10 folders, the 2019 approximate costs of the current PAWDOC system are as follows:

  • Filemaker Pro 18: new £520; upgrade from Filemaker Pro 15 £190
  • Canon DR-2020U scanner: £660 – but this model is probably discontinued: the current model with equivalent functionality can be bought for about £290.
  • Cloud service for ongoing backup: free with BT Broadband; equivalent standalone service – Apple iCloud, for example, £8/month.
  • 1 Tb External hard drive for local backup: Seagate £40
  • 500Gb External hard drive for remote in-country backup: Maxtor £30
  • 128Gb memory stick flash drive for out of country backup: Kingston £15

The total price (excluding the laptop and the Windows 10 operating system which came with the laptop) is £895 + £8 / month cloud backup.

Q59. Is it worth spending the time and money on a personal electronic filing system?

2001 Answer: Ideas formed: Yes, the core benefits of an improved ability to find documents and files – faster retrieval and space reduction – are achievable and do make a difference. Furthermore, these benefits continue to be achievable over many, many years. However, the desirability of these benefits, and the way the filing system is operated is highly dependent on individual preferences and work style.

2019 Answer: Fully answered: Before answering this question, there needs to be clarity on what is meant by a Personal Electronic Filing System (PEFS) because it may mean different things to different people. At its most fundamental level, it’s something most people who have computers do – they put electronic files into folders provided by the operating system. However, the PEFS that is being discussed here is something much more than that. It has three characteristics:

  • Operates as a single system: All files, regardless of size, file type and creating application, are stored in the same single system with the same standards and structure and organisation.
  • Digitises hardcopy: Hardcopies are incorporated into the same single system by digitising them. Any hardcopies that remain are retained either because they are artefacts with special value in the physical form, or to act as temporary working documents.
  • Controls documents: Files are not just put into folders willy nilly. Their existence is recorded and they are given a unique reference in their title so that they can be identified.

These special characteristics mean that an individual has to apply an amount of extra  effort, and to have a certain amount of determination, to operate a PEFS. Some people may not want to work in such a structured way; and other people may not want to expend that time and effort. Such people will feel that it just isn’t worth doing. If you are prepared to do it, however, my experience is that it is definitely worth it. It organises documents and enables you to find them again. It helps you to organise your work generally; and, by its very nature, it automatically builds a long term collection which can be accessed at will. I personally found it so useful that it just became an integral part of my normal day to day work.

Regarding cost, I believe this to be much more reasonable these days and well within the reach of an individual.

Q60. What do other people think about this approach to electronic filing?

2001 Answer: Not started: Although at least three other people/groups (John Pritchard, Dave Harris and the CSC UK Consulting & Systems Integration Information Centre) have tried out this approach, no detailed work has been done to establish their views on its effectiveness and desirability.

2019 Answer: Fully answered: I have done no systematic work to establish people’s views about this type of Personal Electronic Filing System (PEFS). However, I have assisted at least 4 different people / organisations to implement such a system, so their willingness to try it out indicates that they could at least perceive that there might be some potential benefits. The four instances are:

  • My colleague at NCC, John Pritchard, who designed the PAWDOC schema with me. He used the approach until he left NCC in 1990.
  • The CSC UK Technical Library at Slough which applied the approach for about 18 months in 1988-90 using the Aquila application for the Index. The general approach was taken up in the reincarnation of the library in the form of CSC UK’s Consulting & Systems Integration information Centre in Farnborough which was certainly using the same Reference Number schema around 1995-96.
  • A colleague at CSC who worked for me, who used the approach for about 8 months in 1988-9 before leaving the company.
  • Another CSC colleague who used the approach for 5 years in 1985-90 before leaving the company.

I don’t recall any of these people/organisations saying that the approach was not workable or worthwhile. On the contrary, the person who used the system for 5 years said in the summary of his experience with the approach that he “found it to be a very effective way of controlling my own documents”.

Of course these instances and anecdotes provide almost no hard evidence at all. It is probably only my long and highly documented use that gives any detailed insight. But at least the combination of the two sets of material may provide the basis for readers to form their own views.

PAWDOC: Reliability and Longevity

Operating a Personal Electronic Filing System is just an adjunct to one’s main work, and, consequently, it’s at the bottom of the pecking order when it comes to an individual’s time and attention. This combined with the fact that we humans do make mistakes, means that filing tasks may build up, documents may get lost, scans may miss out pages, file titles may include incorrect Reference Numbers etc.. Despite all these problems, experience with the PAWDOC system has shown that it is possible to operate such a system successfully over the long term. It has also demonstrated very clearly that it would be almost impossible to maintain a hardcopy-based personal filing system across a lifetime of work; but that it is certainly possible to do so with a digitised version. The reason is simply that the volume of paper is overwhelming, whereas an equivalent digital collection is eminently manageable.

The very intangeability of a digital collection does, however, present dangers which need to be addressed if it is to survive. Backing-up is essential, and creating multiple backups placed on various media in different and distant locations is a wise move. Technology’s current incessant charge of development, also presents challenges to a collection’s long term readability, and owners must be prepared to perform digital preservation work periodically to keep their hardware and applications operational and up to date.

Specific questions relating to this aspect are answered below. Note that the status of each answer will fall into one of the following 5 categories: Not Started, Ideas Formed, Experience Gained, Partially Answered, Fully Answered.

Q55. Will human errors make the filing system unworkable?

2001 Answer: Experience gained: No, because the number of errors is relatively low and fall mainly into the following categories:

  • Duplicate reference numbers on physical documents (the indexing system precludes duplicate reference numbers in the index) (Wilson 1992a; 2, 1992b: 2.10).
  • Hardcopy documents out of order in the cabinet/box.
  • Archived items not marked as archived in the index, and vice-versa (Wilson 1992b: 2.10).

2019 Answer: Fully answered: Human error will creep into most systems which have human operaters – and probably even more so in personal filing systems which have to be managed alongside heavy workloads. The 2001 answer identified three types of human error discovered in the PAWDOC collection (duplicate Reference Numbers on hardcopies, misfiled documents, and errors in the Index Movements field). In addition to these, the recent checking and Digital Preservation work that has been undertaken on the PAWDOC collection identified several other types of error including:

  • 285 items have been lost over the years – about 1.6% of the total.
  • 33 instances of missing pages have been identified in scanned documents – probably caused by human errors in the course of scanning.
  • 9 records in which text was not copied correctly from emails into a word document (which was my preferred approach to capturing email text for inclusion in the collection) have been identified. This probably occurred because I failed to check that all the text had been pasted in.
  • 5 records where index entries have been inadvertently left empty – probably caused by a mix up in the course of creating new records.
  • 2 instances in which the wrong document was scanned so that the digitised document is not the document that is specified in the relevant index entry.

No doubt there are others. However, despite this, the filing system continues to work successfully, and, over the years, I have rarely come up against such errors when I have been searching for documents.

Q56. What backup arrangements should be put in place to protect the integrity or sheer existence of the filing system?

2001 Answer: Partially answered: A comprehensive collection of all one’s files becomes a unique irreplaceable entity over a period of years. To ensure its availability and existence the following measures need to be taken (Wilson 1992b: 2.13):

  • Regular backup of the index – daily is preferable, weekly is realistic, monthly is essential.
  • Regular backup of the electronic files and scanned imagesÐdaily is preferable, weekly is realistic, monthly is essential.
  • Printout of the index in KWIC (Keyword in Context) format – every six months or yearly (though I have never had software able to do this).
  • Secondary backups of index, electronic files, scanned images and KWIC index stored in a location different to the location of the primary backup media – every six months or yearly.
  • Tertiary backup in a secure environment such as a bank -every six months or yearly (I have not done this yet but am seriously contemplating it).

2019 Answer: Fully answered: Backing up is an essential element in any computer system. It is advisable to have at least two copies, one of which is held some miles away from the master. The PAWDOC backup regime is clearly described in the PAWDOC User Guide; and, to prompt me to actually perform the backups, I have a table with upcoming backup dates in a frame on the wall that is directly in front of me when I sit at my desk. The backup reqime that is applied to the PAWDOC collection is as follows:

  • Cloud: Ongoing backup of new files and changes to files are made to a cloud service.
  • Offline backup to an external drive at home: New copies of the whole collection are taken once a year.
  • Copy on other laptop at home: The back up on the external drive described above is copied to the other laptop in the house immediately after the new copy has been acquired, i.e. once a year.
  • Remote UK external drive: The whole colllection is copied onto this hard drive once every two years and it is stored at least 10 miles away from the master laptop.
  • Remote out of country backup: A copy of the whole collection is copied to a 128Gb memory stick and given to the person who lives in the country concerned, whenever I meet up with that person.

Q57. Are electronic filing systems reliable over very long periods?

2001 Answer: Partially answered: Over the 20 years of this project, the system has been very reliable. However, the following problems have been experienced or are anticipated as the system gets older:

  • Crashes of the index database -recovered either by functionality in the software or by using backups
  • Magneto-Optical disk corruption (has happened to just one disk)Ðrecovered by using backups.
  • Document management system has lost about 30 files – not sure how this happened and it was not recoverable.
  • Longevity of other people’s files – I am sure I could not now obtain some of the items belonging to other people to which I put a reference in my index 10 or 15 years ago.
  • Longevity of web addresses – I do not think that some of the web addresses the index points to will be still live after several years. We have yet to see whether web addresses of journal contents will be reliable over long periods (Wilson 1996a).
  • Electronic files stored in old versions of software when the original application software may no longer exist on your PC, or may have been upgraded beyond recognition. This is a potentially very serious problem over periods of 10 or 20 years or more (Wilson 1997: 1).

2019 Answer: Fully answered: The fact that the PAWDOC system is still fully operational after 38 years does demonstrate that such systems can be reliable in the long term, despite the inevitable loss of some documents or pages within documents.  However, in practice much depends on the diligence of owners and whether they are sufficiently motivated to take regular backups and to perform digital preservation activities on their collections. Taking an overall very long term view, the longevity of such systems relies on the following 4 characteristics:

  • Visibility: Because an electronic filing system (EFS) is, by its nature, intangible and locked away somewhere inside a computer, the first essential requirement for it to survive is for one or more people to be aware of its existence.This can, of course, be achieved by simply telling people. However, PAWDOC’s existence is also fully documented in a Hardcopy User’s Guide which is contained in one of the two archive boxes in my study.
  • Accessibility: Knowing that an EFS exists isn’t the same as being able to get at it; over a period of years laptops become defunct and inaccessible; and backup technologies my cease to work. Therefore, for EFSs to continue to work long term, the platforms they run on must be kept up to date.
  • Integrity: For an EFS to work properly it is necessary to have all the software and data that it uses, in place. Missing data can be very annoying and even disasterous; whilst missing or corrupt application software can preclude the system working at all. Effective backup regimes can help to alleviate this problem.
  • Readability: The data files in an EFS can’t be read unless there is an application that can open them up and display them. Over time, applications get upgraded or may become defunct. Therefore, it is essential to implement a Digital Preservation routine that identifies files in danger of no longer being accessible and that takes steps to rectidfy the problem.

If all these aspects are addressed, an EFS should be able to survive for many, many years.

PAWDOC: Confidentiality, ownership and intellectual property rights

When working for an organisation it is widely recognised that you will need a collection of documents to support your work. In building this collection, any explicit IPR regulations, or stipulations imposed by document owners, should always be complied with; and this includes very highly confidential documents which are probably best left out of the collection. However, if you operate your personal filing system on the basis that it is only for your own personal use, many of the IPR and Ownership issues may be overcome.

When leaving an organisation, individuals may or may not want to take some documents with them depending on the type of profession, stage in their career, their next job, etc.. However, in deciding what to take, they must follow explicit rules and regulations; and they should leave behind any material which is likely to give a significant competitive advantage to competitors.

Specific questions relating to this aspect are answered below. Note that the status of each answer will fall into one of the following 5 categories: Not Started, Ideas Formed, Experience Gained, Partially Answered, Fully Answered.

Q52. How should confidential documents be handled in an electronic filing system?

2001 Answer: Not started: Hardcopy documents can be stored in a vault and the associated reference numbers can point to the vault (Wilson 1992: 2.8).

2019 Answer: Partially answered: The most effective way of dealing with very highly confidential documents is not to include them at all in your personal electronic filing system. However, if you do want to record their existence, they could be included in your index in such a way that the Reference Number or Movement Status field points to their residence in a secure location. If you must have possession of a document itself, then it will be necessary to secure its existence on your laptop or other personal device with a combination of passwords and encryption – provided that satisfies any rules or regulations associated with it.

Q53. How do ownership and IPR issues constrain the operation of a personal electronic filing system

2001 Answer: Not started

2019 Answer: Partially answered: One of the most important principles to apply when assembling a personal document collection is that you deliberately restrict it to your own personal use.  This probably overcomes many of the IPR and Ownership issues related to documents that you haven’t created yourself. With that principle in place, I believe it is recognised that, while one is working for an organisation, you are entitled to have a collection of documents relevant to your work. Having said all that, it is essential to comply with any particular IPR regulations, or constraints stipulated by specific document owners, that you become aware of.

Q54. What IPR considerations have to be taken into account when moving from one organization to another

2001 Answer: Not started

2019 Answer: Partially answered: While one is working for an organisation, you are usually entitled to have a collection of documents relevant to your work. When leaving an organisation, I always felt that, as a consultant, there was a tacit understanding that you were able to keep copies of the documents you had created; but that there was a grey area in which the removal of large quantities of documents only partially related to one’s work, would cause concerns – probably because there was a fear that they might give some advantage to competitors. Herein lies a dilemma for the diligent personal filer: on the one hand it seems a shame to waste all the effort one has put into assembling and indexing a collection of documents, and on the other hand there is the knowledge that ostensibly taking it away when you leave an organisation might encourage a knee jerk reaction to prevent you removing it. To address this issue, two principles should be applied: first, comply with any explicit regulations concerning specific documents or information; and second, leave behind any documents or information that you believe would give a competitor a significant advantage.

PAWDOC: Sharing files

A personal filing system enables the individual to decide what to include in it, what to specify in the Index, and what to include in the file titles. Hence, a personal file system is very specific to an individual, and it is this very specificity that would make it difficult to share an index and the items it represents over the long term.

To address this problem the Reference Numbers in the PAWDOC system were designed to distinguish between different owners and different sets of information within each owner. The thinking was to enable entries for documents in other collections to be included in one’s own Index. It certainly did enable such entries to be included in the Index; however experience over many years showed that it was almost impossible to get access to such documents after one had changed jobs or after many years had passed. Consequently, I stopped including such entries in the PAWDOC system.

Of course, the sharing of a small specific set of files for a relatively short period is much more feasible. Collaborative file sharing has been explored by the CSCW (Computer Supported Cooperative Work) community for many years; and services such as Dropbox are widely available on the net. However, this is not the same as sharing thousands of files on numerous different subjects over many years.

Corporate Document Management Systems have also been widely implemented in recent years and these do enable whole workforces to share an index and the associated files. However, these too cannot be considered to be personal filing systems since they have very specific corporate objectives with supporting regulations and constraints.

In short, the long term sharing of personal indexes and files does not seem feasible or demanded at present.

Q50. Can two or more people share the same filing index?

2001 Answer: Ideas formed: Only with great difficulty, unless deterministic indexing rules are adhered to and controlled descriptors are used. Unfortunately, this probably reduces the effectiveness of the index for all parties.

2019 Answer: Ideas formed: I have come across no evidence to suggest this is currently feasible. Corporate document management systems do enable individuals to share the same index – but such systems do not provide the longevity, portability from job to job, and freedom of choice about what to include, that a personal filing system offers. If such a system were to be developed it would need to cater for three different types of requirements:

  • Objectives: the ability to satisfy the different approaches and preferences of the individuals concerned while providing a coherent uniform system.
  • Individual characteristics: the ability to cater for things such as the different terminology used by each individual, and for the fact that each individual will only have a mental imprint of the documents they themselves have included in the system.
  • Technology: the use of compatible technology by all individuals including things like software applications to open documents, file formats, application versions, and a commonly accessible file store such as the cloud.

Q51. What is the most effective way to enable two or more people to share the same files?

2001 Answer: Experience gained: Make entries in your own index in your own words but use the other person’s reference number in your index instead of creating your own (Wilson 1992: 2.4)

2019 Answer: Experience gained: Two or more people can share files very effectively using a cloud-based service such as DropBox. However, this is probably used mostly for a limited number of files on a specific subject for a few months or years. I have not heard of large ongoing collections of personal files being shared in this way – though I suppose it might be feasible with some sort of shared index which is also held in the cloud. Large Corporate Document Management systems also enable people to share files, but such systems have different objectives, regulations and constraints and cannot be considered to be personal filing systems.

PAWDOC: Portability

Since the early 1980s, office work has become increasingly decoupled from a single static location. Most people no longer have their own offices – in fact, many people no longer have their own desks. Hot desking and working from home is commonplace.  Business travel by car, train and plane is widespread; and working away from the base location in hotels or remote offices is a regular experience for some people. This mobility, and the fact that most office work is now undertaken electronically, continues to drive the development of powerful portable computers. The modern laptop is very light and powerful, and can have a huge storage capacity. The PAWDOC collection is stored on a machine weighing 1.3 kg and takes up just under one twentieth of the total 1Tb capacity of its SSD solid state drive.

Q48. Are electronic filing systems portable?

2001 Answer: Experience gained: Yes, except for the scanner. The software systems run very well on a laptop computer. Most, if not all the electronic files and scanned images can be held on a laptop’s hard disk (which in 2001 would normally have between 5 GB and 10 GB available). If additional storage is required, CDs will meet the requirement.

2019 Answer: Fully answered: Yes – modern laptops have more than enough storage capacity to store all the digitised contents of a personal filing collection; and they have the power and display technology to enable fast searching and easy reading of the selected documents. Such laptops are light weight and eminently portable. Even portable scanners have been available for some time. However, scanning technology is now commonplace and is likely to be available in most offices (often through the office photocopier), so carrying around a portable scanner may not be worth bothering with.

Q49. Under what circumstances does a filing system need to get used away from the base office?

2001 Answer: Experience gained:

  • While travelling in trains, planes, hotels and hot desks.
  • While working for periods of days, weeks or months away from the base office. (Wilson 1992b: 2.9).
  • While at home.

2019 Answer: Fully answered: In addition to the circumstances listed in the 2001 answer (while travelling, while working away from the base office, while at home) I would add the following:

  • While attending meetings.
  • Any place and situation in which the owner is working.
