The Author Files include both General Files and Works Files. The first section, General Files, are where copyright certificates and correspondence from the authors and about the works is found; the section also contains folders of requests from "Aspiring Authors" (works that were never published) and general copyright information. The Works Files contain manuscripts, typescripts, (either complete or fragments), proof sheets, galleys, and title pages of the works submitted for publication. The nature and completeness of the work is indicated after the work's title; TMs refers to typed manuscript; AMs refers to autograph (handwritten) manuscript. At the end of the series are a few card files, the first of which inventories the Kerr-published works alphabetically by author. Subsequent card files are for the books in the Kerr office not published by Kerr, address lists for advertisers and suppliers, a short-lived card file of addresses of those requesting Kerr catalogs, and unidentified cards.
