4. 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.

5. Conversion to Applied Discrete Structures Scan pages of 1989 edition o Text: Reasonable accuracy o Notation: Terrible o Figures: Poor Import into Mathematica o Lots of editing - some student help o Replace Pascal and Ada with Mathematica and Sage. o Upload.nb and.pdf files to wiki. Student assistants: first pass, fixing obvious problems
