Open Educational Resources (OER) are free materials for teaching and learning that can be reused and/or modified (based on the creative commons copyright license). Resources may include textbooks, articles, videos, and other multimedia materials.
Open Access (OA) is access to scholarly material such as publications, journals, and articles. The material is free to use depending on the creative commons license. They cannot be modified; however.
The resources provided in this guide are a mix of OER and OA resources. The main difference between Open Educational Resources and Open Access Resources is whether material can or cannot be modified; both models are openly available to use.
