If you are collaborating with students on making an Open Source textbook, here are some helpful resources for you.
There are a variety ways to find reliable, peer-reviewed Open Access Resources in the UMU Catalog..
1. Access the Open Access Resources via the catalog "Easy" tab option.
a. Add the keyword in the "Easy" tab search box.
b. Once you see the results, you can filter the results (see left hand column filtering options) by OA.
2. Additionally, there are some Open Access resources that cannot be loaded into the catalog. You can click on these directly.
3. You can also go to the A-Z Databases and limit your search by "database type" to Open Access. From these results, you can further limit your search by "subject".
