The first numbering system for films used an F (for film), then F.H. (for family history) or a geographic code, then a number or a letter and number and often a part number. A part number designated a separate film in a film series. Examples: | The first numbering system for films used an F (for film), then F.H.

The second numbering system was just numbers, starting at number 1, often with a part number attached. These numbers were also called "red numbers" because, for a number of years, the numbers were printed in red ink on the film boxes. Again a part number designated a separate film in a series of films. Examples: | The second numbering system was just numbers, starting at number 1, often with a part number attached.

The current numbering system started over with number 1 and new films are assigned the next sequential number. No letters or part numbers are used. As the library now has over 2 million films in its collection, zeros are sometimes added on the front of a film number to make it a 7-digit number, but they are not needed. Numbers are good with or without the leading zeros. For example: | The current numbering system started over with number 1 and new films are assigned the next sequential number.

=== Title Boards === | |||
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. | |||
=== Item Numbers === | |||
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. | |||
=== Targets === | |||
These are documents added either at the beginning of the item being filmed, or on the image being filmed, to communicate details about the record which may not be immediately apparent. There are two types of targets used, technical and quality. | |||
Technical targets gave information about the microfilming processes. Among these were: | |||
*Beginning of roll | |||
*Continuation to another roll of film | |||
*End of roll | |||
Quality targets indicated the condition of the document. These included: | |||
*Tight binding | |||
*Smeared ink | |||
*Damaged document | |||
