The term open educational resources (OER) was first introduced at a conference hosted by UNESCO in 2000 and was endorsed in the context of providing free access to educational resources on a global scale.
OER include a varied range of materials: books, case studies, courses, journals, primary sources, assessments, assignments, reference materials, tutorials, tests, and more.

OER release should be subject to ongoing Quality Assurance process which is transparent and fair, however this is not always the case.
Without preservation of these often one-time start-up OER projects, the initial funding will end after a few years and sustaining the resources will be expensive, the resources may become outdated and the quality gone.
Many do not understand the potential of OER and feel that it threatens their ownership of intellectual property. Also, it takes time to creat and/or locate existing OER.
When it comes to OER the most typical open licenses used are Creative Commons Licenses.
Generally speaking, an open license grants permission to access, re-use and redistribute a work with few or no restrictions.
The toolkit provides a detailed description of Creative Commons (CC) licenses, as well as a four-step guide to choosing, creating and adding CC licences to resources to make them OER.
