RMRL has been documenting all available and accessible Tamil resources including the RMRL collection. MARC21 format is used for cataloguing. RMRL is involved in creating catalogue records of newly published items and also in converting printed bibliographies into electronic format. The library has now migrated its catalogue to Koha which is an open source LMS providing a platform to manage the multilingual database. RMRL has been contributing unique catalogue records in English, Tamil and other South Asian languages to the WorldCat. RMRL has indexed several Tamil periodicals on literature and gender studies.
