I will be in NYC in June and while I'm there I would really like to visit a few bookstores. I would especially like to visit a store with a good range of US history books, particularly 'classic' works, like a nice edition of Bancroft's 'History of the United States'. Ideally, I'm interested in secondhand stores with some character, but I'm open to all kinds of suggestions.
In terms of location, anywhere in Manhattan should be ok for me. Places that are open on Sundays would be great.
Does anyone have any suggestions? Thanks!
