During this period, specifically until 1999, and keeping with IE’s global projection,the library was managed by specialists in different areas. This development, in addition to the change in location, was a key milestone in the library’s history, leading to the creation of a global unit from which all the knowledge accumulated until that point could be coordinated. Traditional library services were put in place, including a manual catalog of existing publications, as well as a digital version created by the I.T. department. Books were ordered through a sequential number system to facilitate their location, a system was established for ordering and lending books and journals in coordination with the directors of each department, and subscription opened to the first databases.
