The personal book collection of the founders, Atty. Benjamin R. Salvosa and Mrs. Evangelina D. Salvosa constitute of the library’s first collection when the University of the Cordilleras, formerly Baguio Colleges Foundation, was founded in 1946. It started with a one-room size library catering to 146 enrollees and its staff. Over the ears, the population grew with the increasing school population. There was then a need for a more expansive and spacious library to house its collection and accommodate its users, thus some rooms of the Main and Science Building were selected.
Since its founding in 1946, the Baguio Colleges Foundation Library expanded tremendously. It was divided into the nine sections: Main Library, Periodicals Library, Law Library, Graduate School Library, Reference Library, Filipiniana Library, Engineering Library, High School and Grade School Library. Great efforts were made to encourage students and faculty members to use the library. Good library service starts with the combined attributes of staff, materials, equipment, and facilities.
On July 1, 2014, UC library was named University of the Cordilleras Libraries.
The library uses the Dewey Decimal Classification System in classifying its library materials. It maintains the semi-open shelf system.
