This series has taken its place as one of the most important popular-priced editions. The "Library" includes only those books which have been put to the test of public opinion and have not been found wanting,—books, in other words, which have come to be regarded as standards in the fields of knowledge—literature, religion, biography, history, politics, art, economics, sports, sociology, and belles lettres. Together they make the most complete and authoritative works on the several subjects.
