So many great collections! The Believer documents the disheveled and decorated bookshelves of poets on their Tumblr believermag:
Poets’ Bookshelves. An ongoing series of posts documenting some of the books collected by our favorite poets. This week: Dorothea Lasky, most recently the author of Thunderbird (Wave Books, 2012). Her website is dorothealasky.tumblr.com.
