OpenSIGLE

OpenSIGLE combines the resources of major European information and document supply centres who have joined together in an association known as EAGLE : European Association for Grey Literature Exploitation.

It provides open access to SIGLE bibliographical references of reports and other grey literature (GL) produced in Europe. Examples of GL include technical or research reports, doctoral dissertations, some conference papers and pre-prints, some official publications, and other types of grey literature. OpenSIGLE covers pure and applied science and technology, economics, other sciences and humanities.
