Start with what we already have! The OSU Libraries is a good place to begin.

While not "free" in the sense that these are subscription based materials, there are many resources that we subscribe to that you can use in your courses instead of asking the students to purchase a textbook or other reading materials.

1. 400,000 Ebooks
2. 82,000 Unique Online Journals
3. 60,000 Streaming Videos

And, if we have the print book or DVD in the collection, place it on course reserves! That way students who are waiting for the text can at least get started with the readings.
