According to createspace, 92 copies of the Sage tutorial *and* the calculus book Differential calculus with Sage have been ordered in the past year, generating $243.30 in royalties for the Sage Foundation. It is hard to tell using the format they give, but I'm guessing that the calculus book sold at most 1/5-th what the tutorials sold, so maybe 75 tutorials were sold? I think this might be more of a question for sage-marketing, but it seems to me that there would be more copies of the tutorial sold if it was marketed better, so I don't know how useful these numbers are. (Not that I know anything about marketing.) Though slightly off-topic, I have a book that uses Sage to discuss the Rubik's cube and similar puzzles. An older version is on-line (with the publisher's permission). I'm told that book was the highest selling math book that Johns Hopkins University press sold about a year or so ago. I don't know if that has changed recently or not. In any case, JHUP is publishing Marshall Hampton and my book on Differential equations and Sage (which is CC licensed), so I guess they are making some money on the deal. > > Thanks for any numbers! > > Cheers, > Nicolas > > [1] http://sagebook.gforge.inria.fr/ > > -- > Nicolas M.
