The series consists of files documenting land title searches regarding mineral rights. The searches determine the previous dispositions of mineral rights prior to issuing a new certificate of title. The files contain correspondence between the registrars and legal firms as well as documents related to searches, such as caveats, certificates of title, mineral certificates, land surveys and plans, and transfer of land documents. The files may also contain copies of court records such as Submissions, Petitions, Affidavits and Judgments.

The collection contains a variety of materials, purchased from Academic Books in five purchases over a decade. The collection includes an unpublished manuscript (1908) written by Alexander MacKenzie on the Peace River District covering the years 1793-1908. The next is a typed letter from R.B. Bennet to John Stocks (1905), the then-Deputy Commissioner of Public Works of the North-West Territories (which included present-day Alberta and Saskatchewan at the time). This letter concerned the rising waters that were beginning to circumvent the Elbow River Bridge in Calgary.

Other records include North-West Territories Gazettes (Volume 18, Numbers 7-14, 1901), a HBC census record of the Saskatchewan District (1872), a HBC census record from the Athabasca District (1873), and a small ledger book used in Dunvegan with several pages at the end used by a child to practice letters and drawing (1891-1925). Attached to the census of the Athabasca District is also a document noting the “division of the Chipewyan Nation” according to the Census taken.
