As a fellow Scribe and Librarian, I whole heartedly agree with Morpheus. I was also always rather peaved about the fact that in 3D, book titles could be made much longer, when you scrolled over the book to see it's name. You could see the entire name in 2D but just could not write a longer title unless you had the 3D client.
Having just installed the KR client, I find the same is true for writing titles with it. I'll have to play with it a bit more to see how the context appears though since my first attempt at writing the material within did not appear in 2D as I intended it to. It seems that it cut off sentences in 2D after being written in KR. That is possibly because the individual lines of the book appear in a gump of the page and are much longer as well, actually allowing for more material.
In that sence, a book written in KR and viewed in KR has much more space to write in, but would be cut short for anyone who views it in 2D. And yes there are still only 40 pages. Eventhough it shows 41, the last page can be written, but will not show in KR or in 2D.
