About the .BOOK domain
What is the .BOOK domain?
As with its sibling extension .author, .book is a "closed generic" registry: Amazon, as the sole registry operator, is the only entity that can register names under this extension, with no application process open to individuals, independent bookstores, publishers, or any other organization outside the company. Amazon's original application for this extension drew a formal protest at the time from Barnes & Noble and other booksellers, who sent letters to ICANN expressing opposition to such a generic term, so relevant to the publishing industry, falling under the exclusive control of a single commercial competitor. The domain's final award came after a private auction held in November 2014, in which Amazon turned out to be the sole remaining applicant, allowing it to secure the extension with no further competition.
