My mom and I are taking a trip to L.A. at the end of the week, sort of a Mother's Day Weekend. Our hotel is in Anaheim, but on Saturday we'll be spending some time in Hollywood. Can anybody recommend some good used book stores? (Not just in Hollywood, but anywhere in the general L.A. area.) Preferably ones that contain a wide variety of subjects and genres. I'm looking for some myself, but so far the only ones I've found seem to specialize mostly in classic literature and art books.
