The collection was reclassified from the Dewey Decimal system to the Library of Congress call number system between 1972 and 1975. In 1982, the Main Library moved into a new purpose-built facility on the Greek Campus (a plot on the corner of Muhammad Mahmoud and Yousuf Elguindi Streets, originally belonging to the Greek community).[4] In 1986, the Library implemented one of the first online catalogs in the Middle East through the German-Belgian Dobis/Libis system.[5]
