Open Educational Resources, or OERs, are
teaching, learning and research materials in any medium, digital or otherwise, that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation and redistribution by others with no or limited restrictions.

SPARC, a global open education coalition, states:
Textbook costs should not be a barrier to education. The price of textbooks has skyrocketed more than three times the rate of inflation for decades. College students face steep price tags that can top $200. ... Using OER solves this problem because the material is free online, affordable in print, and can be saved forever.
The Open Education Conference happens each year in October. #OpenEd22 was virtual with sessions October 17-20. Session recordings are also still available from the 2021 conference.
The North Dakota University System has compiled information about OERs from its member institutions. See the link below for access to other ND universities' OER guides and repositories, and information on conferences and other support from NDUS.
Openly Available Sources Integrated Search (OASIS) is a search tool that aims to make the discovery of open content easier. OASIS currently searches open content from 117 different sources and contains 388,707 records.
OASIS is being developed at SUNY Geneseo's Milne Library.
