The Library of Congress Classification system defines Pacific Northwest for maps (G1464.3-.32) as:
Pacific Northwest - The old Oregon Country, comprising the present states of Oregon, Washington, and Idaho, parts of Montana and Wyoming, and the province of British Columbia
The US local History number F851.7 has:
The Pacific Northwest - Including Washington, Oregon, Idaho, Montana, British Columbia
Hope this is helpful.

Hello folks,
I’ve been asked to come up with collection scope including a specified geographic limit for our map collection perhaps just to the Pacific Northwest, however, the U.S. government does not appear
to have a consistently defined geographic area for the Pacific Northwest. So I thought I would turn to my colleagues to see how you define this region of the United States. Below are a sample of different geographic definitions currently in place by the federal
government.
Census Bureau
Division 9: Pacific
Alaska, California, Hawaii, Oregon, Washington
https://www2.census.gov/geo/docs/maps-data/maps/reg_div.txt
Bureau of Reclamation
Columbia River Basin in Idaho, Oregon, Washington, Montana, Wyoming
https://www.usbr.gov/pn/index.html
USDA, Forest Service
Pacific Northwest Region
States of Oregon and Washington, Including Portions of Del Norte and Siskiyou Counties in California, and Portions of Nez Perce, Salmon, Idaho, and Adams Counties in Idaho

USA.gov
Oregon & Washington
USGS
Idaho, Montana, Oregon, Washington, and Wyoming
Your advice is greatly appreciated with many thanks,
