There was a time, not so long ago, when chain bookstores had a pretty bad reputation. Barnes & Noble and Borders were seen as predators eager to destroy local booksellers -- and neighborhood bookstores were weathering threats from all sides. Megastores like Costco started selling bestsellers and encroaching on local shops. Then came a little company called Amazon, and the rise of online book buying. The indies were struggling to make ends meet, and many had to close their doors.
