The Reports subsystem of Central Geological Database (CBDG) contains catalogue data of archival geological reports from the Central Geological Archives (CGA) in Warsaw, its offices in the PGI regional branches and other archives in Poland. The data were previously stored in older versions of databases run by the CGA, the Geophysics Unit and the Geoinformation Department of the PGI as well as SEGI-PBG. The data were partly collected while the Infogeoskarb system was being prepared.

The new web application of the Reports subsystem has advanced functionalities for data search and retrieval. The Reports subsystem is the largest collection of catalogue data of archival geological reports and contains more than 830 000th records.
