Authoring Open Source Mathematics Textbooks

Despite there being many excellent tools for authoring, producing and distributing open source textbooks, it is still a technical challenge to self-publish a mathematics textbook. This is especially true now that there are so many options for output formats: print, PDF, web, and EPUB to name some of the most obvious choices. Our experiences authoring open source textbooks have led us to meet these challenges with the design of a new authoring language, MathBook XML. In this talk we will describe several textbook projects using this language and give an overview of its capabilities.
