Portals & Gateways
UNESCO/IIEP hosts a Wiki that offers a list of several portals, gateways and repositories. It offers a list of links to OER initiatives, resources and tools. It was compiled following the first IIEP discussion forum on Open Educational Resources (24 October - 2 December 2005). It offers access to a selection of approx. 30 repositories of open learning objects, mostly at the university level.
Free and open resources designed primarily for faculty and students of higher education. Specifically, MERLOT is a growing catalog of online learning materials, peer reviews, learning assignments, and user comments, organized by discipline into specific discipline communities and created to help faculty enhance their instruction, that anyone can use for free. At the moment has more than 14,000 resources. It was developed by California State University Center for Distributed Learning (CSU-CDL at www.cdl.edu).
OER Commons is a teaching and learning network offering a broad selection of high-quality Open Educational Resources, OER, that are freely available online to use and, in most cases, to adapt to support individualized teaching and learning practices. It is the first comprehensive open learning portal where teachers and professors (from pre-K to graduate school) can access their colleagues’ course materials, share their own, and collaborate on affecting today’s classrooms. It uses Web 2.0 features (tags, ratings, comments, reviews, and social networking) to create an online experience that engages educators in sharing their best teaching and learning practices. OER Commons is a project of ISKME, a recognized leader in applying educational research to educational practice.
You will find 7 groups of subject-specific open courseware but also specialized resources for each subject, that is why it is acting as a gateway to specific repositories. It is an annotated listing of publicly available courseware (lecture notes, handouts, slides, tutorial material, exam questions, quizzes, videos, demonstrations, etc) from the world's universities, colleges and other educational institutions. It was created and is maintained by iberry.com, a non-profit private website, serving the international academic community.
The OCW Finder currently shows results from several collections: MIT OCW , Utah State University, Johns Hopkins School of Public Health OCW, Tufts University OCW, Foothill De-Anza SOFIA, and Carnegie Mellon Open Learning Initiative.

The UK's free national gateway to Internet resources for the teaching, learning and research community. The RDN is a collaboration of over seventy educational and research organizations, including the Natural History Museum and the British Library, and builds upon the foundations of the subject gateway activity carried out under the JISC's (Joint Information Systems Committee) . The service links to resources through a series of subject-based information gateways. Although primarily aimed at users in UK higher and further education, the network is freely available to all. It gives access to over 100,000 resources. In contrast to search engines, the RDN gathers resources which are carefully selected by subject specialists in our partner institutions. You can search and browse through the resources, and be confident that your results will connect you to Web sites relevant to learning, teaching and research in your subject area.

Community developed content
ou start by creating a list of books you like. Using this list the site will introduce you to discussions you may want to engage in as well as other members you may want to connect with.
Because the system understands that books are related in different ways (fiction, non-fiction, topical, genre, writer, age, type of plot, scientific area, etc) it can connect you to discussions that may be of interest to you even if the books discussed are not exactly the same as the ones you have on your booklist. The same goes for connecting you with other members. The system can introduce you to others who share your interests even if you haven't read any of the same books. This is usually a great way to get recommendations for new books.
