Various online referencesEdit
- List of mathematics texts including some with open content.
- Other books, some free, some not - theassayer.org.
- Public domain textbooks from the University of Pennsylvania. Lots of old ones here.
- Dozens of online textbooks here although you'd have to investigate the license for each one.
- Wikipedia has lots of useful GPL'ed information, though it needs to be assimilated and organized into a unified whole
- Project Gutenberg has countless texts to which one could link
- For the time being at least, we can only use outside material that is already CC-BY-SA licensed or in the public domain. However, experience on Wikipedia has shown that authors that place their work under one free license tend to be very willing to grant us a CC-BY-SA license, if we ask nicely.
