Apollo is the institutional repository of the University of Cambridge, managed by the Open Research Systems team based in Cambridge University Library. The Repository is committed to store and preserve the University’s research outputs. Research outputs can include, but are not limited to, publications, conference proceedings, book chapters, monographs, theses, various forms of research data (video recordings, spreadsheets, computational scripts, code, images etc.), presentations and others.

This is a subject based repository, that mirrors the data held on the PubMed Central site. Since 2010, the service diversified from PMC and introduced additional content including PubMed abstracts and biological patents. In addition this site acts as an Open Access repository for peer-reviewed research from researchers who have been funded by the Europe PMC Funders Group - submitted via the Europe PMC Manuscript Submission System A range of supporting guidance and background information are available on this site.

This archive is an Institutional Repository for NERC Staff. It contains metadata and full text (where possible) for published papers, reports, maps and other outputs from four of the NERC Research Centres: the British Antarctic Survey, British Geological Survey, the Centre for Ecology & Hydrology and the National Oceanographic Centre. It is also accessible to Staff at NERC's Swindon Office. A RSS feed is available. NORA provides information on research outcomes for NERC's intramural research to the RCUK Gateway to Research system. Subject specialities are atmospheric science, earth science, earth observation, environmental maths and statistics, marine, polar, science based archaeology, technology and e-science, terrestrial and freshwater science. Not all items are available in full-text on this site, however they are linked to subscription based external sites. RSS and Atom feeds are available.
