Open Source Education: Free Textbook Archive
In the spirit of open software, Open Culture is building a list of free, online collegiate textbooks.
College is as much a financial investment as it is an investment of time. While tuition costs tend to be the biggest expense, the cost of textbooks often figure greatly into the total. We've previously documented the remixable textbook option whereby professors can pick and choose excerpts from different texts into an electronic gadget — lowering the price of buying numerous books. Still, those measures can prove costly.
In the spirit of open software, Open Culture has begun to compile a collection of free online textbooks; this “growing collection” includes humanities, but mainly offers science and mathematical primers. This collection is completely legal as the collection only includes works (originally published in print) and now published online for free by the authors.
