The holdings of the CAC reflect Bland's dual career as educator and architect. John Bland was responsible for assembling the materials which now form the archives of the CAC. There are 71 projects from the John Bland Archive that consist of drawings, photographs, and reports. These projects are grouped under series based on Bland's architectural partnerships. Other literary material, such as his publications, lectures, and unpublished papers, offer insight into the plethora of subjects that captivated Professor Bland's interest. The archive is rounded out with articles by others on John Bland and his work, as well as his personal collection of slides, maps, and books.

Personal materials include family correspondence, 1929-ca 1932, and ca 30 cm of class notes and draft papers stemming from his student years, largely at Louisiana State. There are also files of private correspondence, some addressed to Mrs Andreassen, from the period 1975-1980. Andreassen's diaries cover the years 1936-1940, 1945-1952, 1962-1965, and 1968-1976. They record the working day and are interleaved with memoranda and correspondence, often of a personal nature. Professional files vary in nature with each stage of Andreassen's career, but correspondence and reports are consistent elements. To these may be added copies of surveys and inventories of the Louisiana Historical Records Survey, expense accounts and photographs arising from his work for UNRRA, records of archival deposits and drafts on an institutional history prepared as Archivist of CNR, and annual reports written as McGill Archivist.
