Grey Literature

Grey literature comprises a wide range of documents, specifically for example thesis, reports (technical, research, annual, etc.), conference materials (proceedings, posters, etc.), trade literature, educational materials and much more. We recommend to visit pages about definitions and NRGL document typology for more information.

NRGL provides central access to information on grey literature produced in the Czech Republic in the fields of science, research and education.
NRGL is operated by the National Library of Technology in Prague.
