From its beginnings around 1958, the Luis Ángel Arango Library has been involved in activities that seek to improve cataloging, as well as information normalization from different perspectives such as: personal and corporate authors, uniform titles, and geographical names.
In 1986, the library acquired the NOTIS system, with the purpose of automating all its functions and services. Later on, it incorporated the LEMB database (in Spanish, List of Subject Headings for Libraries), which first edition was prepared by the Colombian Institute for the Promotion of Higher Education, ICFES, in 1985, and was later converted to MARC/NOTIS format by Chile’s Bibliographical Information Network, RENIB.
From that point on, the library has been constantly working on updating the List of Subject Headings for Libraries, LEMB, through a committee integrated by post secondary libraries such as Los Andes University, the Communications Faculty at Javeriana University, and Jorge Tadeo Lozano University, among others. As a result of this collaboration, a third Edition of the LEMB List has been produced, as well as a fourth edition in digital format.
