Open Educational Resources (OER)

BASE is one of the world's most voluminous search engines especially for academic web resources. BASE provides more than 150 million documents from more than 7,000 sources. You can access the full texts of about 60% of the indexed documents for free (Open Access). BASE is operated by Bielefeld University Library.

The Mason OER Metafinder launches a real-time, simultaneous search across 21 different sources of open educational materials.

Free and open collection of peer-reviewed online learning materials for higher education.

Courses and assessments from MIT OCW.

One web page for every book ever published. It's a lofty but achievable goal. To build Open Library, we need hundreds of millions of book records, a wiki interface, and lots of people who are willing to contribute their time and effort to building the site.
To date, we have gathered over 20 million records from a variety of large catalogs as well as single contributions, with more on the way. This source is particularly strong in humanities subjects.

The Open Textbook Library is supported by the Center for Open Education and the Open Textbook Network.

This is a course of lessons and practice on the system of English. It is divided into eighty-six sections. Each section covers an area of basic grammar and contains a number of exercises.

These modules are grounded in The Higher Education Quality Council of Ontario’s (HEQCO) A Practical Guide for Work Integrated Learning and represent over 35 hours of rich content that can be used by faculty, career-services staff, and employers to support student learning in applied and work-integrated settings. The modules, licensed under the Creative Commons (CC BY NC 4.0), may be packaged together to create an online course, substantial units of a course, or to supplement WIL experiences within other courses.
