Here’s a list of new (to me) open resources:

• The Inclusive Learning Design Handbook: A resource to help OER creators support a diversity of learning styles and individual needs, developed by the floe – flexible learning for open education project

• GitBook: An open text platform that can sync content with Github.
• MathBook XML: A lightweight XML application for authors of research articles, textbooks and monographs. Also has a recent and promising integration with WeBWork.
• Standard eBooks: Public domain ebooks from sources like Project Gutenberg with “carefully designed and professional-grade” typesetting and formatting.
