Finding OERs

OER resources are bountiful. Finding the right OER which is of the quality you require, however often proves a challenge. These pages aim to provide you with some route markers to find the resources that suit your needs.

Global Open Educational Resources (OER)

Open Educational Resources (OER) come in many shapes and sizes. The body of OER available globally is dynamic. The number of OER available globally is also staggering, making it impossible to create a single definitive database. The lists of sources in this section therefore serve to introduce the scope of OER globally and provide and introduction to some of the major OER. The following structure will be used to present the Global OER (please note that the groupings are not necessarily mutually exclusive):

Learning Objects: Raw materials to create comprehensive learning materials.

Digitised Library Collections Resources:

Open access library material.

OER Encyclopaedia:

Edited by volunteers or invited experts.

Open Textbooks and books:

Digitised traditional texts of collaboratively created texts.
