OpenGrey

OpenGrey is a multidisciplinary European database, covering science, technology, biomedical science, economics, social science and humanities. The records are in English. They include bibliographical data, the SIGLE classification codes with their wording, and possibly an English abstract (starting in 1997). Each record has either an English title and/or English keywords. Document types include technical or research reports, doctoral dissertations, conference papers, official publications, and other types of grey literature. The user is informed of the availability of the document and the conditions of access for paper documents from each supply centre
