Public libraries endowed by private munificence form already a large class, and these are constantly increasing. Of the public libraries founded by individual bequest, some of the principal are the Public Library of New York, the Watkinson Library, at Hartford, the Peabody Institute Libraries, of Baltimore, and at Danvers and Peabody, Mass., the Newberry Library and the John Crerar Library at Chicago, the Sutro Library, San Francisco, the Enoch Pratt Library, Baltimore, and the Carnegie Libraries at Pittsburgh and Allegheny City, Pa. Nearly all of them are the growth of the last quarter of a century. The more prominent, in point of well equipped buildings or collections of books, are here named, including all which number ten thousand volumes each, or upwards, among the public libraries associated with the founder's name.
