Our initial search to find suitable existing open textbooks encompassed the following sites:
- MERLOT
- OER Commons
- Connexions
- Free Technology Academy
- FLOSS Manuals
- FlatWorldKnowledge
- Free Book Centre
- Global Text
- The Saylor Foundation
- Jorum’s collection of of open teaching materials “Open Educational Repository in Support of Computer Science”
- BookBoon (quite a few potential texts at but they are “free as in beer,” not open, and are advertising supported)
- CK-12 Flexbooks (K-12 materials but of very good quality, worthy of examination as exemplars at least)
