began. However, from the 1940s onward a new architectural paradigm, which discarded historical vocabularies and incorporated attitudes learned from Germany and from the studio of Frank Lloyd Wright, stemmed from German émigré Henry Klumb. For 20 years Klumb was sole architect for the University of Puerto Rico, designing buildings for the campuses at Río Piedras and Mayagüez until in 1966. At that time chancellor Jaime Benítez assigned the design of the General Studies Building to the architectural firm of Toro & Ferrer. Other buildings for the university have been designed by architects Antonio Marqués Carrión (sports facilities, 1971); José Firpi (student residence Torre Norte, 1971); the firm of Reed, Torres, Beauchamp & Marvel (new Education Faculty Building, 1974 and the first expansion to the Faculty of Natural Sciences Building, 1978); the firm of García & Landray (second expansion the Faculty of Natural Sciences Building, 1989); GDO Arquitectos (School of Architecture Building, 2001) and Toro Ferrer (new General Studies Building, 2007). In addition to La Torre and The Quagrangle, several buildings in the UPR-RP campus have been added to the National Register of Historic Places, such as the former female residence hall "Residencia de Señoritas" building which now houses administrative offices. Library system The university library serves the research and teaching needs of the university community. It also extends its services to the Puerto Rican community at large. The system comprises eighteen specialized and general libraries, with holdings totaling more than 4,000,000 items, access to which may be achieved through the university's online catalog. Of special interest are the Caribbean and Latin American Studies Library and the Puerto Rican Collection, both located in the José M. Lázaro Building. In addition to the traditional library services, such as reference, circulation, reserves, photocopying, local interlibrary loan, and the compilation of bibliographies and acquisition lists, the Library System also participates in on-line interlibrary loans with many libraries worldwide. Other services include Dial Order, DIALOG, microfilming, reproduction of photographs, library instruction and orientation, lectures, and exhibits. The Integration of the Information Competencies to the Curriculum Projects promotes the development of information competencies around the campus. The Library System offers facilities for the blind and physically handicapped. The graduate and special collections in the Business Administration, Planning, Public Administration, Social Work, and Library Science programs are integral parts of the Library System, but the libraries of the School of Law, Natural Sciences Faculty, and the School
