From the Oklahoma Historical Society website:
The Incorporation Records for the Oklahoma and Indian Territories have been digitized in a joint project with the Oklahoma Historical Society and the Oklahoma Secretary of State’s Office. The ledger books were generated by the Territorial secretary as new businesses and municipalities began conducting business. There are 27 volumes of Oklahoma Territory Incorporation Records and 15 volumes for Indian Territory. Some examples of the entries found in the ledgers include: Agreement & Incorporation, Incorporation Amendment, Appointment of Agent, Dissolution, as well as lease and mortgage transactions. The entries begin in 1890 and continue until statehood is established in 1907.
The creation of this database is sure to be a goldmine for researchers who have hit dead ends trying to research the state of Oklahoma online before statehood! Let us know if you locate anything by leaving a comment below!
