William Warner Bishop

William Warner Bishop (July 20, 1871 – February 19, 1955) was an American librarian who is credited and remembered for his work organizing and cataloging the Vatican Archives, his time served working with the American Library Association, as well as his support of academic libraries. He has the honor of being named one of the most influential librarians in American history.

Early life and career William Warner Bishop was born in Missouri in 1871. He relocated to Detroit, Michigan, when he was seven years old. Bishop went on to obtain his undergraduate degree at the University of Michigan in Classics in 1892 and then earned his master's degree the following year. He taught Greek and Latin from the time he graduated until 1902. He was an instructor at Missouri Wesleyan College, Garrett Biblical Institute in Evanston, Illinois and even had the opportunity to spend a year in Rome between 1898 and 1899 studying Greek and Latin. While he taught he usually worked part-time in the academic libraries. He originally thought that he would like to have a career in education but found himself instead drawn to a career working to improve the quality of library services. It was here that he became interested in helping the library system to serve people as productively as possible. He worked as a part of many committees where he also had the honor of presenting countless scholarly papers that he wrote in regard to the controversial topics of the day. Bishop also wrote several books some of these are: Practical Handbook of Modern Library Cataloging, (first edition 1914 and second edition 1924); Cataloging as an Asset, (1916); The Backs of Books and Other Essays in Librarianship, (1926); Carnegie Corporation and College Libraries. (1929–38)...". He was elected President of the American Library Association in 1918. When his one-year term as president was completed, he went on to serve as President of the Bibliographical Society of America in 1921-23 and in 1931 President of the International Federation of Library Associations... In 1928 he became chairman of the Advisory Group on College Libraries of Carnegie Corporation.

Vatican City Bishop served as the main advisor in helping The Vatican Library to become better by updating the cataloging system it used as well as reconstructing the building the archives were housed in. He chose to request the aid of Charles Martel who worked at the Library of Congress as a cataloger and was considered to be one of the best in his field. With a strong team of people working alongside him, Bishop was able to accomplish his goal. Because of his strong abilities as not only a librarian but also as man who exhibited strong leadership skills and earned the respect of his colleagues, he was able to successfully implement positive change within the Vatican Archives.

Advisory Group on College Libraries Bishop worked to aid college libraries in spending grant money supplied to them by the Carnegie Corporation during the years spanning 1928–1943.

Death and legacy William Warner Bishop was ahead of his time. He believed that the public library as a whole should be made accessible for all persons in the community it served. "In short we librarians are convinced that all printed matter is our province- not necessarily literature alone in the old sense- and that it is our business to get things in print into the hands of every one who can profitably use them- whether he knows it or not". He believed that libraries should be advertised to the public, explaining how what was in the walls could be of service to all citizens; not just scholars or those who had attained a certain level of education. Bishop was also a big proponent of staying ahead of the trends or at least remaining current in library practices. He did not want to see librarians fall behind the ideals of great service and fair practice to all patrons, which would cause a disservice to the instruction he or she represented.

He died on February 19, 1955.
