Portals to Postal History
United States Post Offices

Mike Ludeman

June 2020

The great digital libraries of the Internet have digitized hundreds of books and other publications which can be useful to the stamp collector and the postal historian. Unfortunately, the correct cataloging of many of these publications was less accurate than might be desired, especially for many government publications, making them difficult to locate using the standard search engines of the Internet.
My solution was the creation of a series of files, which I have called Portals, in which I regularly recorded the names of publications I had discovered, and in which I preserved their URL (Universal Resource Locator). This allowed me to quickly return to a publication which I had previously discovered.
This shelf in the Stamp Smarter Library provides the Portals I have compiled for materials relating to the Post Office of the United States. For more information about these Portals, and how they were created, please read the Introduction in the monograph Using Resources for Researching the Post Office Department: 1789-1960 below.
The resources identified and included in these Portals have been collected over the past decade, and some URLs may no longer be reliable. If you find one that does not work, or the expected file is not what is described, or if you know of a resource which belongs with one of these Portals, please bring the necessary information to my attention at mike@ludeman.net, and I will attempt to correct the problem.
