Knowledge Unlatched (KU) is back in the news. Founded as a not-for-profit open access (OA) book publisher by Dr. Frances Pinter, the organization has gone through a couple iterations until re-emerging as a for-profit company headed by Dr. Sven Fund. (Despite its for-profit status, KU continues to use its old URL, with a .org domain.) KU is now hard at work on developing its program, including its business model. A major piece of this, recently announced in an interview by Fund, is the Open Research Library (ORL), which aims to be a comprehensive collection of all OA books, of which there are now (according to KU) about 15,000-20,000, with approximately 4,000 more being added every year. KU can aggregate all these books, which have many publishers, because of the terms of their Creative Commons (CC) licenses, which encourage reuse and sharing. And that is what has set off a seismic disturbance.
