The bookshelves don't work properly with opera and aren't placed very well in windows IE
How about:
Bookshelf I: A, B, C, D
Bookshelf II: E, F, G, H
Bookshelf III: I, J, K, L
Bookshelf IV: M, N, O, P, Q
Bookshelf V: R, S, T, U
Bookshelf VI: V, W, X, Y, Z
...or similar
Could the category sorted library be placed somewhere like:
The Cellar: Coord. 4_1x2_27
or [Unnamed room]: Coord. 4_1x2_6
