Genesis of our current project• Sage Education Day, Cambridge 2009, Rob Beezer and others
talking about open content textbooks.• Al Doerr and I agreed to track down the copyright holder,
Pearson and ask for the rights. They granted it, no questions asked! One condition: Include “Formally published as…” on title page.
• We then decided to solve our students’ $150 textbook problem.

Conversion to Applied Discrete Structures
• Scan pages of 1989 editiono Text: Reasonable accuracyoNotation: Terribleo Figures: Poor
• Import into Mathematica o Lots of editing - some student helpo Replace Pascal and Ada with Mathematica and
Sage.oUpload .nb and .pdf files to wiki.
• Student assistants: first pass, fixing obvious problems
