Texas Government Code Section and and Texas State Library and Archives Commission authorizes agencies to retain records on microfilm or electronically stored images. Microfilm is a high-resolution film in roll or fiche form or mounted onto aperture cards containing micro-images. Document imaging involves the conversion of hard copy original documents or records to an alternative media.

Records with permanent or long term (more than 20 years) retention periods or archival requirements may be retained on microfilm. Offices choosing to microfilm records may obtain those services through a purchase of services. This chapter contains guidelines for microfilming. See Chapter 7, “Electronic Records,” for information on electronic imaging.
