 The repository of the KarRC RAS Scientific Archives was established using the EPrints system.This system permits creating and maintaining repositories with a required structure and set of metadata for storing collections of electronic documents, and provides a ready-make toolkit for filling in the repository and controlling access to its contents.The user interface in the original version of the software is in English, but the set of language options can be expanded, so an add-on to EPrints enabling the Russian language was developed.
