The clerk of the district court shall keep records to be called the appearance docket, the trial docket, the journal, the complete record, the execution docket, the fee book, the general index, and the judgment record. Such records may be compiled, filed, and maintained on a computer system. Effective not later than October 1, 1992, provision for dockets and records of the district courts shall be established by rule of the Supreme Court. The journal may be compiled and filed on microfilm. The recording of all instruments by the roll form of microfilm may be substituted for the method of recording instruments in books. If this method of recording instruments on microfilm is used, a security copy on silver negative microfilm in roll form must be maintained and filed off premises under safe conditions to insure the protection of the records. The internal reference copies or work copies of the instruments recorded on microfilm may be in any photographic form to provide the necessary information as may be determined by the official in charge, and shall meet the microfilm standards as prescribed by the State Records Administrator.
