The book contains 146 plats documenting property boundaries, land ownership, and leasing on the Pine Ridge Reservation from 1936 to 2005. Changes to the plats are recorded on transparency sheets placed over the original pages. Each plat in the digitized version includes three scanned images: the transparency over the original, the transparency alone, and the original alone.

At the beginning of the book is a faded page outlining the color-coded shading system used to indicate land status. This is followed by a typewritten copy of the "Order of Restoration, Pine Ridge Reservation," dated June 10, 1936, and issued by Harold L. Ickes, U.S. Secretary of the Interior (1933–1946). The order cites the Act of May 27, 1910, and the Presidential Proclamation of June 29, 1911, as its foundation and announces the restoration of undisposed surplus lands on the Pine Ridge Reservation to tribal ownership, under the authority of the Indian Reorganization Act of June 18, 1934.

The remainder of the book consists of plats of the Pine Ridge Reservation, home to the Oglala Lakota people. The reservation is located in southwestern South Dakota, encompassing Oglala and Bennett Counties and parts of Jackson County. Its boundaries were established by the Act of March 2, 1889 (25 Stat. 888).
