The bulk of the collection focuses on Lee's architectural career, consisting of architectural drawings and sketches, project plans, proposals, incoming and outgoing correspondence, specifications, contracts and financial recordkeeping, and other records related to construction, renovation, rehabilitation, and other architectural projects in which Lee was involved.

While many of these projects took place in Lawrence, Kansas--including in downtown Lawrence, with the University of Kansas, and for the restoration of the Union Pacific Depot in North Lawrence--Lee also worked elsewhere in the region, particularly in northeastern Kansas and western Missouri. Lee worked on both commercial and residential projects. An extensive collection of architectural drawings related to many of these projects is located at RH AD 11; additional oversize materials have been physically separated and are located at RH MS R425.

There is also some materially generally related to Lee's career, not to specific projects, as well as some materials from his teaching duties at the University of Kansas. Additionally the collection includes some materials related to Lee's personal life, including correspondence and particularly records related to his cycling hobby.

Spencer Research Library processing staff have kept the collection in much the original order in which it came but have intellectually organized through this finding aid materials related to each other, such as grouping commercial architectural projects together versus residential projects or University of Kansas-related materials.
