While it does not mention Sage explicitly, the article by Doob in the August AMS Notices (http://www.ams.org/notices/201407/rnoti-p756.pdf) "Open texts on the Web, taking the next step" does say this:
"There is a wonderful example of an electronic textbook that moves beyonf the pdf format. Rob Beezer's new online version of his linear algebra textbook [4] incorporates many of these advantages. It's worth a good look." [4] http://linear.ups.edu/html/fcla.html John -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
