Originally title boards were used to identify the microfilming project number and sequential film number in the project. Soon after microfilming began additional details were added to the title board indicating where the records were filmed, the records being filmed, the camera operator, and the week-ending date. | Originally title boards were used to identify the microfilming project number and sequential film number in the project.

Several different records may be included on a single roll of microfilm. When this was done a title board was filmed to indicate the next record on the film. Early title boards did not contain sequential numbering, but these item numbers were added later on. | Several different records may be included on a single roll of microfilm.
