The county recorder creates abstracts that contain the history of property ownership by providing a true chain of title by geographical location. They contain the date and character of instrument, book and page number where instrument was recorded, entry number of instrument, and legal description.

These are legal instruments recorded by the county recorder concerning mining. They include the following: Notices of locations, Mining deed records, Mining claims records, Proof of labor records, Mining mortgages, Mining abstract records, Mining transfers and relocations. In some counties mining records are compiled separately, while in others they are part of the "Official records."
