BASE - Bielefeld Academic Search Engine
BASE is one of the world's most voluminous search engines especially for academic web resources. BASE provides more than 240 million documents from more than 8,000 content providers. 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 index is continuously enhanced by integrating further sources / content provider (Become a content provider). BASE is a registered OAI service provider.

International Baccalaureate Welcome to the new International Education Research Database! This reference database is a free online resource for students, researchers, teachers and others involved in all aspects of international education research. The IERD is a collaborative effort by a range of different parties interested in the field, and its success depends heavily on the additions of its users. While the IB research team will continually update this resource, new references from our users are highly encouraged. Because it is a referencing resource, rather than an online library, the IERD does not hold the actual full text publications, however in many instances a link is provided to the full text or to the publisher's website. If you would like to add a new reference, please register first.

Supporting the evolution of Open Access publishing Sustainable, high-quality OA publishing requires either funding to be available to pay for Article Processing Charges, sponsorship, or suitable embargo periods. OUP operates two different open access models: OA at OUP
