Producers of grey literature
Research Institutions (Academy of Sciences, Public Research Institutions, Private Research Organizations)

These institutions also organize or, through their staff, participate in both Czech and international conferences, from which is conference paper or book of proceedings a standard output, a type of grey literature balancing on the edge between published and unpublished literature.
Their task is to provide targeted support for research projects, to collect from a professional point of view the key and important type of grey literature - project reports (partial, progress and final reports). Thanks to the close cooperation with the Academy of Sciences and the universities, it has been shown that reports from projects often containing valuable information are a type of grey literature that is almost inaccessible to experts.

Other types of grey literature, such as annual reports, research reports, studies, analyzes, and research and grant reports, are also emerging at universities.
