This thread by Rodders -- First editions in your collection. -- got me interested in finding out what books members had that were signed by the author to them personally, either at book signings or by some other method.
I only have one -- a paperback copy of The Grey King by Susan Cooper. And I wasn't even there for it, and so didn't meet her (one of the regrets of my life). A friend very kindly got it signed for me at a convention.
I also have a couple with dedications from people who weren't the authors. Two Doctor Who novelisations were signed to me by Tom Baker when I won a competition as a kid. And The Shark Watcher's Handbook was signed to me at a wildlife charity event by freediving goddess Tanya Streater (sighhhh).
