One of the benefits of open licensed materials that I often cite is that they will always be free (unlike the other free stuff on the Internet…Many of us have experienced the unfortunate consequences of great content and tools that were once free becoming available only on a pay basis. And while it every publisher’s right to make that decision, a shift in strategy often poses big problems for educators.).
A great case in point is Flat World Knowledge’s open licensed textbooks. The company recently decided to no longer provide open, free access to the many textbooks they offer.
However, these textbooks had already been published under a non-revocable Creative Commons Attribution-NonCommercial-ShareAlike 3.0 license.
So now the good folks at the Saylor Foundation have made these textbooks available for use, modification, and distribution.
And this site makes these books available in easily editable doc formats, even better than what Flat World Knowledge had ever done! Thank you to everyone who made this possible.
