The National Academies Press recently announced that it was making over 4,000 PDF versions of its books available for free download. This is a very interesting development, especially considering that they previously were allowing much of this content to be accessed on a page-by-page basis on their website.

I checked it out this morning and downloaded The Teacher Development Continuum in the United States and China:Summary of a Workshop.

So far, I’ve really enjoyed it. Go check out the free books!
