Anyone pining for the long-distant giant SF library sale in September will be thrilled to hear that the library's expanded to a second annual sale which is going on this very weekend. The sale is smaller than the tried-and-true version but contains over 75,000 books, enough to fill an entire high school parking lot. There's some gorgeous stuff there, and with Michele and Christine's help I found several as-new hardback copies of beautifully illustrated children's classics for my niece. If you're in the Mission and looking for something to do, I recommend checking it out.
