Release dates are taken from official sources and online retailers. In cases of discrepancy, the earliest date is used. Please be aware there may be some early retailer-exclusives. Also, while these are accurate to the best of my knowledge, retailers may have the books on the shelves or sent out earlier than the noted release date so they may be widely available ahead of the dates listed.
