I have always talked about book acquisitions. Ever wonder what happened to all the books after I have finished? I keep about half of them and donate the rest. The thrift shop has been a reliable recipient of my discarded books but I have found the Friends of the San Francisco Public Library donation center an even better place. This venue is singlehandedly responsible for the merchandises at the two locations of Reader’s Bookstore at the Main Library and in Fort Mason. From the outside, the only hint that the bookstore at Fort Mason Center isn’t your average used bookstore is a cart, often stacked with bags or boxes, under a sign reading, “Book Donations.” Sales at the Readers Bookstore, which gets its inventory solely through donations, keep climbing while other stores struggle to survive or face closure. Everything—from signed, first edition copies to recent best-sellers—is priced about 20 percent lower than at other used bookstores. The donation center in the Mission hosts a $1 book sale on every second Saturday of the month. All proceeds from book sales go to the library, as the stores are all manned by volunteers. I would drop off the books and browse their store, end up spending money, but at least it’s for a good cause.
