Sources for a study of American attitudes toward poverty are abundant, varied, and accessible. There are many approaches to the topic and, out of the vast literature bearing on the subject, the individual researcher must select those works that strike him as most representative and pertinent. The particular sources I have used for specific phases of the problem are indicated in notes for each chapter, and the major works consulted in the preparation of this book are listed in the Bibliography. I have not thought it desirable to divide and subdivide the Bibliography into numerous classifications, but I should like to call the reader's attention to certain works that have proved unusually helpful.
Owing to the nature of the inquiry I have relied mainly on printed works, but Mr. J. G. Phelps Stokes of New York kindly put at my disposal his large collection of correspondence and papers dealing with charitable and reform activities since the 1890's. I have also utilized various unpublished reports in the archives of the Community Service Society of New York. I found some uncatalogued material on "Poor" in the New York Public Library Annex, and certain nineteenth-century pamphlets not readily obtainable elsewhere in the Newberry Library in Chicago.
My basic sources were the writings of humanitarian reformers such as Joseph Tuckerman, Robert M. Hartley, Charles Loring Brace, Josephine Shaw Lowell, Amos G. Warner, Jane Addams, Jacob Riis, Edward T. Devine, Robert Hunter, John A. Ryan, and Florence Kelley. In addition to the well-known books of Miss Addams and Riis the key works in this category include Brace Dangerous Classes of New York, Mrs. Lowell Public Relief andPrivate Charity
