A non-profit organisation that brings together research organisations. It has developed the CERIF (European Research Information Format) standard exchange format for research information, i.e. an international standard for communication between national information systems that should enable the easier exchange of data on ongoing research. It is recommended by the European Commission. The latest version of the CERIF format was published in September 2008.

An information network for preprint resources in the basic and applied sciences, primarily in physics but also including subject areas such as chemistry, biology and life sciences, materials science, nuclear science and engineering, energy research, computer and information technologies.

A portal that disseminates official information from the US government. Searching is performed using the catalogue.

In April 2008, the DaREnet portal became a component part of the NARCIS (National Academic Research and Collaborations Information System) science portal, developed by the Royal Netherlands Academy of Arts and Sciences. Its users can find information about research, programmes, projects, research workers and institutions together with their profiles.

The NARCIS portal can be searched using the Google engine. This project’s budget is EUR 6 million and it is subsidised through the 7th Framework Programme of the European Union. It uses the URN:NBN identifier.

The OpenDOAR project also produces statistical charts.

This ‘system for information on grey literature in Europe’ is a multidisciplinary European database covering science, technology, biomedical science, economics, social science and humanities. OpenGrey is operated by INIST-CNRS, and combines the resources of the major European information and document supply centres that cooperate with this system. OpenGrey also includes conference preprints from our partner GreyNet International’s annual conferences on grey literature.

This is a registry of ‘open access’ repositories created by the University of Southampton. It offers searches for repositories by key word, country, software, source type and content. The search results from the repositories are displayed as thumbnails of the repositories’ websites. It provides statistical data and graphs and was created under the E-prints platform – a platform for the creation of open access repositories, e-prints courses and educational materials.

The GESIS (Gesellschaft sozialwissenschaftlicher Infrastruktureinrichtungen) institute has created the SOWIPORT information portal, which includes grey literature and ‘open access’ publications from the field of social science. The SOWIPORT concept is based on the ‘information cycle’, which divides information into three groups according to the activities performed.
