The Northwest Philatelic Library is based in Portland, Oregon.
The library was originally established as the Harold Peterson Philatelic Library, part of the Oregon Stamp Society. In 2003 it became a separate legal entity in its own right as the Northwest Philatelic Library, Inc.[1]
The library is governed and managed by a volunteer Executive Board of three officers and four directors-at-large.
The collection comprises over 3000 books and around 200 philatelic journals.
The library publishes a journal, Book Reports.
