The George R. Bartholick Papers collection includes architectural drawings, maps, correspondence, contracts, financial records, memos and reports, construction records, photographs, slides and microfilm. Bartholick and his associates generated these materials during the course of business of designing and building architectural structures. There are also a small amount of records pertaining to Bartholick's personal life and interests.

Bartholick’s career included many small commercial, residential, and public construction projects. The majority of these projects took place in northern Washington State. Bartholick is best known for his larger projects, which focused on the remodeling of existing structures rather than construction of new buildings. These projects include the Western Washington State College/University Long Term Planning & Old Main Remodel, Whatcom Museum Remodel, Woodland Park Zoo Remodel, Pike Place Market Remodel and the Fairhaven Revitalization planning project.
