NRGL Typology of Documents

The classification of documents itemized for the NRGL according to the individual criteria can be found in the document 

When processing the classification of documents it was to decide whether to include patents to the type of documents that will be in the depository. We have made an analysis to this problem which resulted in a decision that patents themselves will not be included in the repository, but only information and documents where patents are referred to. Complete analysis can be found in a document in NRGL repository.

The information resources researched to create the classification of documents for NRGL are listed in the separate document attached to this record in NRGL.

A mind map according to the type of documents describes the types of documents and in this way extends the basic mind map in this aspect.

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.
