Open Textbook Catalog from University of Minnesota
https://open.umn.edu/opentextbooks/
The University of Minnesota has created an Open Textbook Catalog as “a tool to help faculty find more affordable textbook options.” The site goes on to say that all textbooks in the catalog are:
- Openly Licensed. Acceptable licenses include Creative Commons Attribution, Attribution-Share Alike and Attribution-Noncommercial-Share Alike or similar. Some books may fall under a No-Derivatives license if the publisher offers an adequate customization program.
- Complete. Only complete books, similar to traditional textbooks currently on the market, are included. Materials such as lecture notes, online courses, or drafts, are provided only as supplements to textbooks listed in the catalog.
- Suitable for Adoption Outside the Author’s Institution.
- Available in Print. Because most students still prefer print textbooks to digital, all textbooks include a print option, generally for $40 or less. In some cases, textbooks without a print-on-demand option may be included if they are sufficiently easy and inexpensive to print locally.
