In their own words
CORE
CORE is a multidisciplinary discovery service for scholarly work gathered from repositories, preprint servers and journals. Its search covers research papers, journal articles, preprints, theses, dissertations, conference proceedings, reports and books. CORE says its collection holds 449 million searchable papers, including 57 million full texts. Researchers and the public can search this material; developers can use the API for real-time access to metadata and full texts. The CORE Dataset supports downloading data for analysis and text mining on an organisation’s own infrastructure, though access is limited to users representing organisations registered in non-sanctioned countries. Individuals can use the API instead. CORE Discovery is available as a browser extension, repository plugin and API, and CORE Recommender suggests related articles in repositories, journal systems and web interfaces. Free API access costs nothing, subject to rate limits of one batch request or five single requests per 10 seconds. Starting membership costs nothing for data providers. The service describes itself as not-for-profit and community-governed.
