Subject fields in which the collection is particularly strong are lumbering, railroads, maritime, and Portland. Learn how to search for photographs in the online catalog or go to photograph gallery.

Vertical Files
The Research Library’s Vertical File Collection includes nearly 4,000 subjects on state and local history and 1,500 biographies and genealogies of prominent Oregonians. The files are indexed in an in-house card catalog and cover such diverse topics as historic homes and buildings, churches, ethnic groups, cities and counties, Portland neighborhoods, railroads, historic trees, and maritime history.

Scrap Book
The Scrapbook Collection contains 350 volumes that span one hundred forty years of Oregon history (1850s-1980s), which is profiled in letters, menus, programs, and other ephemera, and especially in newspaper articles from around the state. Thanks to an extensive conservation effort, the collection is available on microfilm and in bound preservation copies in the Research Library.

The Scrapbook Collection was originally indexed by the Works Progress Administration in the 1930s. A biography card index located in the Research Library lists individuals by surname. The subject index, however, is now incorporated into our online catalog. If your subject search brings up a scrapbook entry, click on that entry to reveal the precise citation.

In addition, researchers can access filmed copies of Oregon decennial census records (1850-1930), territorial census records for Oregon, Washington, and Idaho, documents connected with 19th-century exploratory and surveying expeditions, Superintendent of Indian Affairs’ records for Oregon and Washington, and records of the Russian-American Company.

A special feature of the collection is the collection of Sanborn Fire Insurance Maps (see the Sanborn Fire Insurance maps of Portland-1 and the Sanborn Fire Insurance Maps of Portland-2) which present detailed information on the city in approximate 10-year intervals from 1879 to 1965.
