CORE - Search platform for open access documents

Many organizations are developing their own institutional repositories where the faculties / researchers are submitting their copy of published paper as per respective publisher's policy and giving open access to all in most of the cases.

As per BOAI (Budapest Open Access Initiative) definition, ''Open access'' means 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.

For such open access documents CORE (https://core.ac.uk/)  is a search service which contains 126,687,400 open access articles, from over tens of thousands journals, collected from over 3,673 repositories around the world. It also searches articles published in open access environment by well known publishers such as Elsevier, Springer etc. Being open access, documents are available full text.

CORE aggregates research papers from data providers from all over the world including institutional repositories, subject-repositories and journal publishers. This process, which is called harvesting which allows to offer search, text-mining and analytical capabilities over not only metadata, but also the full-text of the research papers making CORE a unique service in the research community.
