The Postal Service has updated its own history book.
Publication 100, The United States Postal Service: An American History, traces the organization’s evolution from the colonial era to the digital age.
The 144-page book includes several new sections, including “Diversity, Past and Present,” “Unusual Delivery Methods” and tables of historical postage rates.
Other sections cover the different modes of transportation used to move the mail, the rapid changes between the 20th and 21st centuries, stamps and the Postal Inspection Service.
The publication can be downloaded from the PolicyNet site and the Postal History section on usps.com, and print versions can be ordered through eBuyPlus.
