Do you want an easy way to make your first step into the Open Educational Resources (OER) ecosystem? Consider simply doing an inventory of materials you are already using that might be replaced with OER. For the longest time I taught an early American Lit course for which my students paid too much for a reader with a nice cover and nearly 300 out of the 700 pages students weren’t required to read. Upon closer review I found that most of the readings are in the public domain. 335 typed pages later (with lots of help) and a little bit of fancy .pdf formatting, I was able to provide students with a dynamic, no-cost OER version of a reader that perfectly matches the curriculum. The only addition is the set of links to author biographical headnotes that were already available to students at no cost via the college library. While public domain is only one way to find and create your own OER collection, it can begin by simply taking a look at the copyrighted materials you are already using and might be replaceable with open material.
