One of the first clear statements of the Public Library as a business enterprise, involving certain amounts invested by a city with the expectation of certain definite returns. The paper refers particularly to the San Francisco Public Library, of which the author, Frederic Beecher Perkins, was then librarian but its conclusions are general, and hold good to-day. It was read at the Lake George Conference of the American Library Association, in September, 1885. Frederic Beecher Perkins was born in Hartford, Conn., Sept. 27, 1828, a grandson of Lyman Beecher. He left Yale in sophomore year to study law and was admitted to the bar in 1851, but graduated at the State Normal School in 1852 and devoted himself to literary and educational work. In 1880-87 he was librarian of the San Francisco Public Library. He died in Morristown, N.J., Jan. 27, 1899. He was the father of Charlotte Perkins Gilman. There are in the United States about 5,000 public libraries of 300 volumes or more. Returns of their present conditions are very imperfect, and must therefore be summed in the following crude way:-- Annual cost much more than $1,500,000 The books in them are many more than 13,000,000 Books added yearly are many more than 500,000 Books used yearly are many more than 10,000,000 These institutions, therefore, represent a large money investment, and a very extensive and active educational agency. Not all of them by any means are "free public libraries,"--_i.e._, libraries supported by taxes or endowments for the use of all. But a considerable portion of them are. It may now be justly said that no town of importance is respectably complete without a free public library any more than any town whatever without a school. The San Francisco Free Public Library was founded in 1879, and was advancing with creditable speed towards a size and usefulness corresponding to the position of San Francisco, among American cities, until the present city government suddenly cut down its annual appropriation to bare running expenses, leaving no allowance for buying new books, or even for replacing old ones worn out.
