In those constantly arising questions which form the subjects of essays or discussions in all institutions of learning, the well-furnished library is an unfailing resource. The student who finds his unaided mind almost a blank upon the topic given out for treatment, resorts at once to the public library, searches catalogues, questions the librarian, and surrounds himself with books and periodicals which may throw light upon it. He is soon master of facts and reasonings which enable him to start upon a train of thought that bears fruit in an essay or discourse. In fact, it may be laid down as an axiom, that nearly every new book that is written is indebted to the library for most of its ideas, its facts, or its illustrations, so that libraries actually beget libraries. Some of the endlessly diversified uses of a well-equipped library, not only to scholars but to the general public, may here be referred to. Among the most sought for sources of information, the periodical press, both of the past and the current time, holds a prominent rank. When it is considered how far-reaching are the fields embraced in the wide range of these periodicals, literary, religious, scientific, political, technical, philosophical, social, medical, legal, educational, agricultural, bibliographical, commercial, financial, historical, mechanical, nautical, military, artistic, musical, dramatic, typographical, sanitary, sporting, economic, and miscellaneous, is it any wonder that specialists and writers for the press seek and find ready aid therein for their many-sided labors? To the skeptical mind, accustomed to undervalue what does not happen to come within the range of his pet idols or pursuits, the observation of a single day's multifold research in a great library might be in the nature of a revelation. Hither flock the ever-present searchers into family history, laying under contribution all the genealogies and town and county histories which the country has produced. Here one finds an industrious compiler intent upon the history of American duels, for which the many files of Northern and Southern newspapers, reaching back to the beginning of the century, afford copious material. At another table sits a deputation from a government department, commissioned to make a record of all notable strikes and labor troubles for a series of years, to be gleaned from the columns of the journals of leading cities.
