How do you arrange your bookshelves?

[WoundedThorns]

i have one shelf above my clothes in my closet - i can barely reach it! i'm afraid its going to buckle b/c its already looking a bit.. concave. my arrangment makes sense in my head. all the authors are grouped together. satire is grouped together. theres a genocide section, bestseller, Polish history/memoirs, required reading for highschool, etc etc. i also try to group them according to size.

Books

My bookcase is dark brown and black and the Wordsworth Classics Collection looks wonderful in it, but I arrange my books according to author, language and top ten of my favourite books. My favourite ones are in the front row on the left, guarded by a toy hedgehog.
