Effective usage of information accumulated over decades of geological exploration requires a tool that allows cataloging, describing, and providing access to both paper and electronic versions of the materials. Despite gradual digitalization of all the major geological exploration processes, there still remains large volume of the materials from previous years on paper media (technical reports, projects, etc.). They continue to be systematically digitized, while new reporting materials are generated in digital form. In addition, thematic scientific articles and publications are annually published. How to combine all the materials and to ensure quick and convenient access to them? There exist various ways to achieve this goal. The Vilyuisk Geological Exploration Expedition (VGRE) of PJSC ALROSA has taken the path of developing a dedicated information system «EFB GRK» designed to store and get access to the information on geological reports, scientific works, articles, etc. Each type of the documents is provided by its own attribute information; several types of the documents are grouped into thematic sections. The system allows one to obtain information on the availability of the projecting and reporting documentation in the archive funds with ability to order and receive and to trace the movement of such documentation.
