We live about 9 blocks from the library, within walking distance, so my need to acquire books is not quite so intense. However, the Friends of the Library book sales always find me searching for myself and for those special books that I think might appeal to a friend, child, etc. Book stores, especially used book stores, always attract me when we are traveling.
As for books, was it this site where people recommended The Elegance of the Hedgehog? If so, what was there about the book that attracted you? I read amost half way through, more out of curiousity than anything, and am taking it back today. Not my cup of tea.
