Scope and arrangement
The collection consists of Weitenkampf's correspondence and his writings. The letters, spanning the years 1888-1962, include those received by Weitenkampf and drafts of his replies. A portion of the letters relate to Weitenkampf's official duties at the NYPL. There are rarely more than a few letters from any one individual except for the following: Samuel P. Avery (1822-1904) a merchant and art collector, Edwin D. French (1851-1906) an engraver, and Julius J. Lankes (1884-1960) who was a printmaker specializing in woodcuts. The rest of the collection consists of Weitenkampf's own writings, both published and unpublished. Two of manuscript works -"Social History of the United States in Caricature" and "American Life in American Prints"-are valuable for locating visual source material for American history. "Living in One Man's Reading" is a typed collection of quotations that appealed to Weitenkampf. The copies of his published works are all annotated by Weitenkampf with corrections or additions to the text. There is also an 8-volume scrapbook containing clippings of articles written by Weitenkampf, clippings mentioning him, and a few letters from editors concerning his articles.
