Well my part of SantaThing is done- I got the name of the person for whom I'm selecting, and I selected a book.
Luckily, my giftee has tastes remarkably similar to my own- I was a little worried I'd get someone who read horror, or science fiction, or historical fiction, or romance, or westerns, or some other genre that would present a challenge. Even so, I'm a librarian, and I could always tap my good old readers-advisory resources if need be. But in this case, he likes literary fiction! And he hasn't read the second-best book I've read this year. So that's what he's getting.
I don't want to say what my selection was because there is an off-chance he might read my blog. One thing I really like about this SantaThing thing is the opportunity to explore other users' libraries and chat with them. It's been fun to read about what people like, make new LibraryThing connections, check out their libraries and come up with ideas. Well done, LibraryThing!
