The library had its humble beginning in the year 1925 when the Institute was founded. The library then was one room affair and it catered to the few pioneer students and faculty members, who at that time required relatively simplistic needs.

In 1965, the Mapúa Library is housed in three places: 1) the Main Library on the fifth floor of Building E in Avenida Rizal, 2) the Intramuros Branch Library on the fourth floor of the Administration Building in Muralla St., Intramuros, Manila, and 3) the High School Library in Doroteo Jose St., Sta. Cruz, Manila.

At present, The Mapúa Institute of Technology Library comprises the Main Library and two branches, namely, Architecture Library and Mapúa - Makati. Mapúa officials, non-teaching staff, faculty members, students, alumni, and outside researchers with referral letters may use the libraries.

Mapúa Main Library and one of its branches are housed in Intramuros Manila, the other branch is in Makati which operation started in 2001; 1) the Main Library is located at the second floor, West Building 2) the Architecture Library at the fourth floor, South Building and 3) Mapúa-Makati, Library at the third floor, West-Wing of the School Building in Makati.

The main library and its branches, fully air-conditioned, monument the Institute's desire to give students and faculty the best in library facilities. Each of the three libraries carries materials suited to the courses offered namely, Architecture, Chemistry, Chemical Engineering, Mining, Mechanical Engineering, Civil Engineering, Electrical Engineering, Computer Science, etc.

To fulfill the instructional and research needs of the faculty and students, the library maintains adequate volumes of books, highly paid and free subscriptions, complemented with vertical file materials, collection of maps, non print and digital materials, undergraduate/graduate theses collection and other pertinent materials that support the curricula of the school.
