In my last post I talked about a textbook sprint with teachers in South Africa, remixing their own content with Siyavula and Connexions textbooks. The teachers worked with our textbook editor that automatically creates EPUBs (for mobile viewing), saves textbooks to github for sharing and repurposing, and supports mathematics and textbook features like notes, examples, equations, and homework problems.

Now I am including some links in case you would like to play with the editor, work with the source code, and see the user interface designs we are working toward.

• Textbook Editor Demo (Chrome only): Brand new! Pre-Alpha! Some nifty features are hard to find, but we have UI designs to fix that coming up. You must have a github account and log in with your credentials. They get saved in a cookie locally in your browser and passed to Github. OAuth is also supported, and should work in a couple days.  You won’t be able to save your edits on the demo book since you don’t have permissions. Use the chrome browser for now until we get bugs worked out for other modern browsers.
• Code for the editor on github. Feel free to fork the code and start developing. We even have a bunch of bugs you could work on. : – )
• Latest designs we are working toward
  
• Whole book 
• Just the HTML5 content editor
