CORE’s mission is to aggregate all open access research outputs from repositories and journals worldwide and make them available to the public. In this way CORE facilitates free unrestricted access to research for all.

CORE harvests openly accessible content available according to the definition:

By 'open access' to this literature, we mean its free availability on the public internet, permitting any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the internet itself. The only constraint on reproduction and distribution, and the only role for copyright in this domain, should be to give authors control over the integrity of their work and the right to be properly acknowledged and cited.

Philippine Studies: Historical and Ethnographic Viewpoints is an internationally refereed journal that publishes scholarly articles and other materials on the history of the Philippines and its peoples, both in the homeland and overseas.

It believes the past is illuminated by historians as well as scholars from other disciplines; at the same time, it prefers ethnographic approaches to the history of the present. It welcomes works that are theoretically informed but not encumbered by jargon. It promotes a comparative and transnational sensibility, and seeks to engage scholars who may not be specialists on the Philippines. Founded in 1953 as Philippine Studies, the journal is published quarterly by the Ateneo de Manila University.
