Open Textbook Joins the Family

Today we are pleased to announce the launch of http://www.opentextbook.org/, a place to list and keep track of news about textbooks that are open in accordance with the Open Knowledge Definition — i.e. free to use, reuse, and redistribute. We welcome participation in the project and if anyone has a textbook or notes they’d like to see listed or would like to be a contributor to the site please head on over to http://www.opentextbook.org/.
