In 2018, the Society released a new work dealing with Puerto Rico's postal history during the period of the Spanish American War. This fascinating period of philatelic history is detailed in great depth in this new publication. "Puerto Rico During the Spanish American War, 1898-1900" was awarded a Large Gold and received the Postal History Society's Literature Award at the 2018 APS StampShow in Columbus.


Prepared from years upon years of extensive original research, the series of works known as "Napp's Numbers" are classics in the realm of philatelic literature associated with the U.S. Possessions. Now in four Volumes, the material within can best be summarized in the image below.


The Volumes may be ordered from the author at the following address: Joseph M. Napp, 5 Knollwood Drive, West Orange, NJ 07052
