From another topic i got the idea of trying to put together a list of known historical books and sort them based on what subjects they MAY give XP for(but specifically not try to rate their quality or level or even if they´re tractatus or summae), because this would be a very nice help for alot of SG or players who wants to use real books as basis for in game ones.
Dire, I have a list of 1000 books on an excel sheet that I found, starting from the sites you said. It is by no mean complete (It's a work in progress!) and I haven't got around to put abilities that could be linked to each of them, but I would gladly send it to you.
I'll see if I can put it in a googledoc somewhere and post a link for everyone.
