Thanks. I think the comment about the "about us" section is spot on.. Will need to work on making that clearer. The problem, as always is that once you've looked at something a thousand times, it makes sense to us, but not to the users, which is why the peer reviews are so helpful.
On the TOC & Transcriptions, it certainly makes sense to be able to jump directly to the relevant section (assuming the reader wants the text version, and not the images, and I should be able to add a secondary image group link as well in side the TOC). I'll play with that for the sections I've transcribed thus far. Then, it's just a matter of typing to get the rest of the book in... And then the fun starts with 30 years of updates to catch up on!
