I will be traveling to Los Angeles for the first time later this year and would cherish some tips regarding where to find the best book shopping. I am not really interested in the big box retailers like borders or barnes and noble, unless they have a particularly strong film section. No, what I want to find in L.A. are it's discarded books. The books that someone got rid of and were saved by some devoted book seller so that I could find them and bring them home to join the books on my shelf. We will have a car and a lot of time, so searching the entire region is not out of the question. Stores that focus on Art, in particular Film and Photography would be of most interest but my curiosity spans all topics. Thanks in advance for any suggestions; I look forward to hearing from you.
