Books I have bought more than once:

I have a lot, but some memorable ones: I bought a second copy of Pull of the Moon by Elizabeth Berg and gave it to a friend's mom for her 50th birthday. I'm still replacing all books written by Tamora Pierce that I left behind when we migrated, as well as several by Terry Pratchett, Barbara Kingsolver, and Diane Duane.

I honestly don't remember how many copies I have ever bought of Good Omens by Gaiman and Pratchett, as well as By the Sword by Mercedes Lackey and the short story collection Book of Enchantments by Patricia Wrede. I just keep losing them... (Also replacing Wrede's Enchanted Forest Chronicles.)

I bought Quirkyalone by Sasha Cagen and someone liked it so much so I gave it away. I have since bought another copy. I also bought this collection of poems again after giving my old copy to a friend: The Wesleyan Tradition: Four Decades of American Poetry ed. by Michael Collier.

And last year I broke down and bought a copy of The Urge to Jump by Trisha Ashley, which I lost and is out of print, so I was getting desperate. (At the top of my ultra-favorites list, along with doubly-bought Tam Lin by Pamela Dean and Surviving the Applewhites by Stephanie Tolan, and yet-to-be-reboughtConfess-O-Rama by Ron Koertge. Which is next.)
