Open Access (OA) describes scholarly literature that is digital, online, free of charge, and free of most copyright and licensing restrictions.
Open Educational Resources (OER), on the other hand, are teaching, learning, and research materials in any medium -- articles, lesson plans, course materials, audio/video recordings, etc. -- that reside in the public domain or have been released under an open license permitting no-cost access, use, adaptation, and redistribution by others. (Look for materials with the open Creative Commons licenses CC BY, CCY-SA, CCBY-NC, or CC BY-NC-SA.)
While OA and OER are created for different purposes, both OA and OER are vital for reducing or eliminating legal and financial barriers to education and the open exchange of ideas. Open Access articles can be part of the mix of resources used in OER.
Affordable Learning Georgia (ALG) is a USG initiative. Its site has a tutorial on Finding Free and Open Resources. The site includes links to a variety of sources of OER and Open Access materials including OER LibGuides.

Open Access (OA) describes research literature that is free and available "on the public internet, permitting any users to read, download, copy, distribute, print, search, or link to the full texts of [research] articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the internet itself," according the Budapest Open Access Initiative.
"The only constraint on reproduction and distribution and the only role for copyright in this domain should be to give authors control over the integrity of their work and the right to be properly acknowledged and cited.”
The OA model includes the following components:
Remember, while OA is "free" to access, there are still costs for the author to publish the work.
