Unlike existing bookstores, the Publisher receives full aggregated information about the instructor who assigned the publication, the students who purchased a copy, what students liked the about the book, which parts they spent the most time on, and which points the author made they found confusing (all of course as allowed by university policies and governing law). This information may be useful to sales reps in apportioning credit, to your marketing department to tune advertising, and to editors and authors to improve subsequent editions and to choose new titles.
Fascinating.
