the connexions blog: How to control for quality in Connexions?:

"Here at Connexions, all content is published under a CC-by license, which is as non-restrictive a license as possible while still recognizing and attributing work to the author. That means that it is legally possibly to re-use content. Of course, we go one step further in publishing all content with a standardized format to make 'frictionless remix'* even easier (it's hard to remix a .pdf with a Powerpoint presentation, for example)."
