After spending 6 weeks with the four different sizes of bookshelf posters on my wall (40×30 in – full size, 30×20 , 18×12, 15×10), last week I came to these conclusions:

• While the full size version is easiest to see and read, the next size down – 30×20 in – is still perfectly usable;
• Even the two smallest sizes provide sufficient detail to be able to distinguish between books and to find them in the iPad.
• Hanging the posters vertically so it appears as if the books are stacked one on top of the other doesn’t present a problem – in fact it makes it easier to read the book titles; however it might be better to remove the edge of the shelf running vertically down the poster and perhaps replacing it with a shelf at the bottom of the stack.
• As with ordinary books, its more convenient to view the bookshelf posters at head height; and it’s interesting to anticipate that a system displaying digital versions of the posters would enable shelves to be switched to the preferred height at will.
• The posters can be presented together in different combinations and arrangements, for example, the poster of a particular shelf can be horizontal or vertical and can be placed at the top or bottom of a group of posters. This would be easy to replicate in a system managing digital versions of the bookshelves
•  Like the posters, digital versions of the bookshelves could be duplicated and displayed in other rooms or locations.

With these points in mind I decided to put the four different sets of posters to the following uses:

• The second biggest size posters have become my permanent visible images of the books I have scanned and which I no longer have physical copies of. They are arranged in a 40 x 30 in IKEA RIBBA frame which is on my study wall directly ahead of me as I sit at my desk. Being able to use the smaller-than-full-size posters has made it much more feasible to do this – the full size posters would have taken up too much of the wall space. I now have a much more constantly visible view of the spines than I ever had before when they were on bookshelves behind my desk amongst a lot of other material.
• The third biggest size posters have now been arranged on a sheet of white paper and placed underneath the plastic desk pad on which my keyboard and mouse sit and on which I write longhand on occasion. This provides an unobtrusive decoration and demonstrates the reproducibility of the electronic bookshelf. The picture below shows the framed electronic bookshelf posters, the version under the desk mat, the book PDF files and an opened file on the adjacent computer screen, and the iPad showing thumbnails of the same PDF files.
  
• The smallest size posters have been arranged in a 20 x 16in Wilko frame (see below) and given to my son and his wife as a housewarming present for the library area of their new house (not sure how much they will enjoy this but it had to go somewhere…!).
  
• The largest, full size posters have been stored at the back of a large picture frame that I have in my study (see Poster Management journey) in case I should want to use them in future.

In assembling the sets of posters as described above, I took the opportunity to vary the way the individual posters were displayed and to think about how they might appear on a large scale display or roll of electronic paper. Given that many arrangements are possible I included a tag line at the bottom of each one to identify the title of the collection (‘Col’) and the particular arrangement of that collection (‘Rig’). An example is shown below:

There is undoubtedly some synergy between some of the points that have emerged from this electronic bookshelf exercise and in the way that mementos might be displayed, and I intend to think about these when I start the next phase of the Memento Management work described elsewhere in this site. In the meantime, however, my current exploration of the Electronic Bookshelf has come to an end. Perhaps when electronic paper becomes sufficiently cheap, and when an App is available to create, manipulate and arrange the images of book spines and covers, I’ll attempt to replace my framed poster version with the real thing.

In the last post but one, I described how it was pleasing to have full size poster replicas (40×30 inches) of the shelves of books I have scanned, in easy to see positions on the wall in front of my desk. Since then I have begun to wonder just how small these poster replicas could be to provide the same experience. Therefore, as a final phase in this journey, I’ve had the poster set reprinted in three smaller sizes (30x 20 in, 18 x 12 in, 15×10 in) and positioned them in the remaining wall space in my study as shown in the pictures below. Over the next couple of weeks I’ll mull over how the different sizes compare and try to come up with a view as to whether a miniature representation can provide a similar experience to that provided by a full size representation.

The original aim of this investigation was to display virtual images of books on a wall and to be able to call up the full text of any one of them to read. The two ends of this objective – display of a virtual bookshelf, and the ability to read the full text of any of the books – have been achieved. However, the integration of the two ends is, as yet, a manual process requiring the user to choose a title from the virtual display, to open up the iPad SideBooks application, and to find and open the required title.

I’ve briefly thought about a variety of ways that this process might be automated. The original notion was to use e-Paper and to be able to touch the image of a book spine to bring up the full text on a separate screen. In the absence of e-Paper, I toyed with the notion of using Image recognition via an iPhone App, but I couldn’t find an App that would use the text recognised to open up another application. I then started thinking about voice recognition and tried out the Apple Siri voice recognition facility on the iPad. Frustratingly, although it will very effectively open up the Sidebooks application just by the user saying “SideBooks”, Siri is not yet able to search for and open up files within applications. This was confirmed to me by an Apple Chat  support person – though he did advise me that I should inform Apple of my requirement via a Feedback form, which I duly did.

That’s as far as I’ve got. Voice recognition does seem to be the most promising approach – and I guess it’s quite possible that Apple may enhance Siri to call up files, sometime in the future. In the meantime, I expect I’ll be able to just about get by in manual mode!

Before scanning all the books I took photos of them on their bookshelves and had full size posters made of the images. The poster print of the shelf of Paperback  books had two images of about 88 cm (37 inches) in length and roughly 24 cm (10 inches) in height (slightly more than the largest book). After completing the scan of the Paperbacks back in July, I cut out the two poster images, fixed them on some stiff cardboard using miniature bulldog clips and found a couple of spaces on the study wall facing my desk as shown in the image below.

Having had several weeks to ponder them, I‘ve found it pleasing to have them there. I have much better visibility of these books than I had previously as I now look at them every time I sit down at my desk; and it took relatively little effort to achieve and has not taken up any valuable space other than areas of previously blank wall. Of course an electronic and customisable display of the virtual books would have been preferable – but this low-tech version serves much the same purpose.

After completing the scans of the Work and University books last Sunday, I duly cut out the poster prints of those two sets of books. The University books poster is relatively small – some 39 x 32 cm (15.5 x 12.5 inches) and was relatively easy to fit onto the now increasingly crowded wall facing my desk – see below bottom left.

However, the Work books poster, at 114 x 31 cm (47.5 x 12 inches), was far more difficult to place. I was even considering putting it on the wall behind my desk under the bookshelves – or even on the empty bookshelf where the books originally sat – until I had a lightbulb moment and realised the poster didn’t have to be horizontal. Since the titles are normally printed down the spine, they will appear horizontal – and be easier to read – when the poster is turned vertically! Obvious really – but I just hadn’t seen it up to that point. Anyway that made finding a space a whole lot easier and I finally selected a very visible spot between the window and the existing bookshelf as shown below.

So now I still have my books around me, and I can access their contents very easily on the iPad; and I also have two empty bookshelves which I can use for other things – a welcome benefit since I have very little spare storage space left in my study.
