“Grey Literature” in Electronic Archives

Abstract

The term „grey literature“ is used for documents disseminated through non-traditional channels. As a general rule, these documents are accessible outside the book publishing and distribution system. In recent years, this kind of literature is in high demand, in so far that the "grey documents" often contain most up-to-date information. They are stored in institutional electronic archives – repositories. In the report is introduced the most popular electronic archive - Open Grey and the repositories of the Balkan countries, incl. Bulgaria.
