While I was in Portland to represent the APS at PIPEX in May, I visited the Northwest Philatelic Library and met with its new president, Orlie Trier.
The library is in the basement of the Oregon Stamp Society clubhouse. I was there during library open hours just prior to a meeting, and the library was bustling. In between helping library users, Orlie showed me the library’s call number system. It is a homegrown system, but remarkably similar to the modified Library of Congress call number system used by the APRL. Most items are shelved by geographic area, with the rest shelved by subject. In the photo, Orlie and I are standing in front of the library’s strong air mail collection. The NPL’s catalog of books and journals can be searched online.
