The root of the complaint centers on digital rights management, which makes it difficult for a reader to switch an e-book from one e-reading device to another – for example, to move a book from a Kindle, the Amazon e-reader, to a Kobo, the one sold by indie bookstores.
The indie bookstores are saying that’s hurting their business.
"We are seeking relief for independent brick-and-mortar bookstores so that they would be able to sell open-source and DRM-free books that could be used on the Kindle or other electronic ereaders,” Alyson Decker of Blecher & Collins PC, who is serving as lead counsel for the bookstores, told the Huffington Post.
The suit claims that Amazon entered into confidential agreements with the six publishing houses. E-books sold by all six publishers come with the digital rights management lock that makes it difficult to move them to different devices.
“Currently, none of the Big Six have entered into any agreements with any independent brick-and-mortar bookstores or independent collectives to sell their e-books,” the plaintiffs write in their suit. “Consequently, the vast majority of readers who wish to read an e-book published by the Big Six will purchase the e-book from Amazon.”
