From 1914 through early 1942, the Gregg Publishing Company used a printers code on the verso (reverse side) of a Gregg book title page. In a few instances, the printers code appeared at the end of a Gregg book. If you know how to read the printers code, in most cases, you will be able to determine the month and year of the press run for your copy of a Gregg book.These codes indicated the print month and year, NOT the date that the book was first published. Many Gregg Shorthand books with identical text and Shorthand plates have many different print runs with different printers codes.
This document will show you how to determine the Month and Year of a Press Run for a Gregg Publishing Company Book for books printed from 1914 through early 1942.
This paper was updated on 12-18-11 to include new information discovered about the use of the month and year code in the printers code through February 1942.
