Friends: Rice University in USA is hosting a great open education resource initiative called OpenStax. It provides college level textbooks which can be downloaded at no cost if one wants (but a donation will be appreciated) or one can order a print copy at a small price. Please see <*http://openstaxcollege.org/staxdash http://openstaxcollege.org/staxdash*>.
