I had very little to do with it (last semester I taught during the staff meetings so I was a bit out of the loop). From what the course director said it was really based on the cost. I teach at a SLAC with a lot of first generation students who rely on student loads. One of the profs apparently mentioned it and then they went whole hog on it because we didn't like the current book all that much. Basically, they took a book that existed and added at least 2 chapters and then customized the rest. I don't know to what degree they customized it but I do know that wherever possible they added links and references to campus resources to make the book more relevant.
