- The number of leaves in the manuscript. This is required by the BookReader. In the context of the Walters collection, it doesn’t make sense to just grab the number of <surface> elements in <facsimile> (which is what I did the first time), because there are images of the fore-edge, tail, spine, head, and in some cases where the bindings have flaps, an image of the flap closed. We removed those images from the group (although important, they would not make sense within the context of a page-turning version of the manuscript) and then counted the number of images remaining.
- The title of the manuscript: title[@type=’common’]. The Walters manuscripts have several different titles, but for the purpose of the BookReader – the title to display at the top of the main window – the common title made the most sense.
- The height and width of the page images. The first version of the BookReader hard-coded these numbers in, so the best I could do was to use measurements from an example page and hope that the other images in the manuscript weren’t too much different. However, I know that the images are frequently different sizes. So being able to pull the measurements for each individual page image is very useful.
So, updates to the manuscripts are coming very soon. Once they are up I will (finally) publish a post that explains the workflow in more detail and includes all the files and documentation one would need to create their own Digital Walters BookReaders, or to do the same kind of thing with their own materials.
