Although the bookselling community of New York City is much depleted from its heyday, there still are independent bookstores out there. Unfortunately, there has also been a lack of resources available to discover and visit the stores that do exist. This site, while not on the level of the old guides, can help with that.
While the data here are kept up-to-date to the best of my ability, I make no promises about the accuracy of locations or other details presented. If you spot an error, or I've missed a shop, please let me know by email or twitter. Based on the "Hack Spots" website by @jllord.
