Potentially relevant bit from the Higher Opoprtunity Education Act's textbook provision: http://content.efollett.com/HEOA/library/HEOATextbookProvision.pdf http://content.efollett.com/HEOA/library/HEOATextbookProvisi... Provision C.1.c: Publishers are required to provide [to the professor or other book chooser]... >A description of the substantial content revisions made between the current edition of the college textbook or supplemental material and the previous edition, if any. I'd like to see this information made public in a reliable manner. It's well and good that the professors should be enlightened about the relevant content changes, but the spirit of the HOEA is to make textbooks more affordable and purchasing more transparent. If that's really the end-goal, then forcing publishers to make that information public and consumer-facing should be the true requirement. Until students have that, they're beholden to the professors (who may have ulterior motives) when making the purchasing decision.
