I love bookcases. While checking out Oddee.com's list of cool bookshelves my jaw dropped when I came across the Staircase Bookshelf. (More photos at the link.)
I'm in love. I love visiting the huge libraries on my school's campus and nothing makes me feel more at home than seeing large amounts of books. This is probably because I grew up with a lot of old books in my room. (No one in my family remembers why the old books in the family were delegated to bookshelves in my room while I was an infant, but I grew up thinking that at home I was supposed to be surrounded by reading material.)
Here's the whole list for your bibliophilia related pleasure.
