Ex Libris is a wonderful little collection of essays about books, reading, and words written by Anne Fadiman. In my favorite, The Joy of Sesquipedalians, Fadiman writes about archaic or not often used words and the delight one can have when discovering them. In another essay, Secondhand Prose, Fadiman writes about the joy of finding bibliographic gems in used bookstores, a favorite of mine as well. Broad in range, the collection includes essays on joining libraries upon marriage, political correctness, food and literature, plagiarism, and much more.
If you are bookish in any way, I highly recommend you read a copy of Ex Libris. You won't regret it, I promise.
