The National Library moved to its current location in the UNAM campus in 1979 . However the Reserves Collection ( see below ) stayed in a special room at St. Agustine 's Church . The building was damaged during the 1985 earthquake and as a consequence it was decided to build a new annex to the current National Library building . The new annex was inaugurated in 1993
