I can't even tell you how much I love Harvard Book Store. But I'll try.
They have a choice selection of the best books! The good ones are not hidden amongst the mediocre/bad ones, they ARE the books there. As a result, it's sometimes hard to get out of there without making multiple purchases...
The staff do their own recommendations, and tell you a little about the books, which is nice when you're just browsing for something good to read. They actually do an exceptional job of making displays there, really picking out some exciting new books, making it a great shopping experience.
And then there's the downstairs...
Used books and the sort of surplus books discounted from publishers. They have a fair selection of foreign books, but not great. The used books are very well organized, and they are super picky about buying, so the selection is great. They're not inundated with low quality books (in fact, they have none!). So if you're coming to sell your books, be aware that they'll probably not buy many because they only buy the few they need. Also know that the buying hours are limited, so you may want to check before you head in unsuccessfully.
They also have a great selection of art books, social commentary, etc. A really diverse collection, and of the best quality.
Check it out for yourself and enjoy!
