The RMPL Catalog is found on the David Straight Memorial Philatelic Union Catalog hosted by the American Philatelic Research Library.

The Philatelic Union Catalog brings together the holdings of 13 philatelic libraries. Catalog options include the ability to search an individual library’s holdings or search across all libraries to find that elusive research item.
