Welcome! The University Libraries offer many resources that can assist faculty, staff, and students with online distance learning. There are many resources available for free around the web, as well.
Open Educational Resources (OER) are educational resources including textbooks, lectures, media, software, exercises, etc. that are freely available. Faculty may visit the OER subject guide for additional information on using OER.
Note that these sites most likely will not have your instructor assigned textbook. Rather, they are intended to supplement it.
