As a gift marking the retirement in 1970 of James L. Harrison, the 16th
Public Printer of the United States, the
U.S. Government Printing Office in Washington, D.C., produced a unique leatherbound, slipcased set of 5 volumes autographed by all 5,939 employees of the GPO. Obtaining the signatures of that many people, and having them bound in such an elegant and luxurious way, must have been a very time-consuming production for the GPO, one of the world's largest printers. The volumes vary from 125 leaves to 180 leaves. Each subsection is hand calligraphed with an original black & white photograph tipped in. The opening section, "Office of the Public Printer," has two tipped-in photographs.
From the photographs and the department names we may glean a lot regarding the staffing requirements of each department at the time. Of course, between 1970 when Harrison retired, and 2021 when I wrote this entry, there have been many dramatic changes in the way that information is recorded, published, and distributed, resulting in staffing changes at the GPO. As a result, the set provides an unusual record of the GPO as it was in 1970. According to the Wikipedia article the GPO began operations on March 4, 1861 with 350 employees, and reached peak employment of 8,500 in 1972.
According to eeoc.gov, in 2021 the GPO workforce totaled 2314 people.
