(save the children tag used non-ironically, possibly for the first time ever)

Got books you want to get rid of? Got a book addiction you want to feed but don’t have a lot of money? This is your chance. SwapSF, best known for their outrageously huge, successful, and fun clothing swaps are doing a book swap this weekend. Same rules apply: Bring books for $5 entry, or come as you are for $10. Either way you get to take home as many books as you want, drink coffee and booze while it lasts, listen to great music, and very possibly get lucky with the hottest hipsters in San Francisco.
Bonus points on this one: They’re creating a library for Covenant House—a homeless teen shelter in Oakland.
