Subseries I: General Letterpress Copybooks, 1881-1919

Subseries I: General Letterpress Copybooks, 1881-1919, contains 42 volumes of letters composed by Frick over the period of 1881-1919. Correspondents are indexed alphabetically at the front of each volume. In most volumes, guide numbers noted at the top of each page indicate the page number of the previous and/or next letter addressed to the correspondent at hand. Additional copies of outgoing letters were sometimes filed alongside their incoming counterparts in the Henry Clay Frick Papers, Series II: Correspondence, but this was not done consistently by Frick's office staff, and generally only in later years.
