If you're looking for a way to combine two of your favourite things -- shopping for books and being an awesome person -- might I suggest that you donate a book to the Hurricane Katrina-beleagured Harrison County library system? The Dewey Donation System makes it oh-so-easy, and Glark has created extra incentives with draws and prizes through Glarkware and TWoP.
I'm also sweetening the pot in my own small way. If you make a donation to Dewey (or if you already have), just post about it in the comments section of this entry. After the Dewey Drive is over, I'll do a draw of all the comments and I'll give each of ten random commenters a fine mystery offering from the boxes of books that still clutter my front hallway. Give a book, get a book. That's a pretty sweet deal, if I say so myself.
So... ready, set... well, you know.
