The Gerald W. Williams Regional Albums consist of images and ephemera assembled by geographical regions. They were acquired and compiled Williams in the course of his work as a Forest Service sociologist and historian and due to his avocational interest in the history of forestry and the history of the United States, especially that of the Pacific Northwest region.  The albums document popular tourist destinations, national parks, the natural environment, prominent natural and architectural landmarks, forests and forest operations, mining, trains and railroads, early towns and cities, prominent citizens, and human activities, such as public events, hunting and fishing, and everyday life. More than 650 images from selected Oregon albums have been digitized as part of the Gerald W. Williams collection.  Gerald Williams worked for the U.S. Forest Service from 1979 to 2005 as a sociologist (1979-1998) and historian (1998-2005).

The Randolph Linsly Simpson African-American Collection consists chiefly of photographs dating from circa 1850 to 1970, but also includes printed illustrations, original artwork, documents and printed ephemera that provide a record of black history in the United States for the period circa 1770 to 1970. The focus is on African-American subjects, but the collection also includes the work of black photographers, as well as images of white men and women, many of whom were associated with the abolitionist movement. Collected with a broad scope, the images provide information about individuals at all socio-economic levels and include people of all ages and gender. They represent the work of professional photographers in various regions of the United States and some European countries, and the image formats present in the collection reflect the development of photographic processes, beginning with Daguerreotypes and extending through mid-twentieth century formats.
