A crucial element of RMRL’s vision is the preservation of its collection for posterity. One of the main aspects that RMRL concentrates on is preserving existing material in alternate formats, for which the library has acquired specialized equipment. The collection is being systematically preserved through archival microfilming and digitization following International standards. Methylene Blue Test, a crucial test for determining the archival quality of microfilms is performed for microfilms made and processed at RMRL.
RMRL is involved in digital restoration of manuscripts. The Notebooks of Srinivasa Ramanujan were published after digital restoration at the RMRL Laboratory.
