These shots are from the CK save for the last one, obviously ingame. Note that I use doccdr's Book Covers Skyrim mod, as I intend EBM.2 to work along with it. So far it seems the book covers all fit nicely together.
As you can see there are still many holes on the shelves, which shall be filled either by books I still have to bring back or by mine in some cases. The books are sorted by categories in the library (History, Geopolitics, Religious, etc) and by themes in the shelves (War of the First Council, Daedra, epics, horror/love/thieves... stories, etc). I think it is rather convenient this way. I should also be adding bibliographies listing the books and where to find them, and I plan to retexture all the bookshelves to add little signs reading their theme, with a simple color code as well.
I thought I'd add items in the shelves as well but it seems to be more complicated to achieve than I'd thought due to physics: everything collapses beyond logic and it's all a mess. The place should still be cozy, and if I can I'll try to add some nice paintings to decorate the walls.
