One of the main missions of ULAKBIM is to develop products to reflect the scientific knowledge of Turkey. One of the most important studies conducted in this context is the TR Index (carried out under the name of National Databases-UVT until the end of 2013), which was developed in accordance with international standards in order to enable researchers to access national and scientific content electronically.
The TR Index being created by ULAKBIM consists of journals in the main fields of Science and Social Sciences, and subfields of Dentistry, Pharmacy, Engineering, Basic Sciences, Health Sciences, Veterinary Medicine, Social Sciences and Humanities.

The national scientific journals constituting the scope of the TR Index are selected by the committees consisting of specialists and academicians in the relevant fields and ULAKBIM TR Index experts according to the Journal Evaluation Criteria

TR Index can be scanned through the web page since August 2000. In addition to the bibliographic information (article name, author, abstract, etc.) of the articles in the journals included in the index, full text of the article can also be accessed depending on the participation agreement signed between the directorate of ULAKBIM and journal editors.
