The Heading Tracker arose out of the need to help libraries sync their bibliographic headings already under authority control with new Library of Congress updates. Library of Congress authority records would be updated, making changes to the authorized form (1XX heading) but would not provide the old authorized heading as a see reference (4XX heading). Because the old authorized heading did not exist in the authority record the bibliographic record which contained the old authorized form could not be automatically changed to the new authorized form.
An optional process with the MARS 2.0 authority control software that tracks changed headings in the Library of Congress authority database and delivers the changed heading as a see reference (4XX) to Backstage’s automated authority control clients. It was developed to compensate for certain integrated library system’s inability to connect updated authority records with bibliographic authority headings. The see reference was created with an option to hide the reference from the OPAC by using the subfield, ’$w’. It is also marked as a local see reference by the use of the $5. As with most Backstage MARS 2.0 functionality, the client has options in how they want to deploy this functionality.
The following is an example of a Library of Congress authority record with a, "Heading tracker", see reference in it. The subfield $w and the local heading designation are in Bold:
In this example, a name authority has been updated to include a death date. The Heading Tracker software has automatically added the old Name with just the birth date is retained.

In this example, a title authority has had it’s authorized form replaced to remove corporate publishing information. The Heading Tracker has recorded these changes, to update your bibs.

In this example, a subject authority has been changed. If the Heading Tracker had not retained the old authorized heading, it would have been impossible for an automated process to update this heading.

You have several options if you choose to use the Heading Tracker Software.
- Display in public access, or not. The default will be to not display.
- Create an undifferentiated or generic '''''''see'''' reference, or not. The default is to create the reference.
- Clean up '''''''see'''' references (other than a 430) by making the second indicator of that tag blank, in compliance with Library of Congress standards. The default is to not adjust the LC-provided indicator.
- Run a second file without Heading Tracker data, directly after the first file, to remove the Backstage-created '''''''see'''' references. This provides the connection between old and new headings when importing the files to your ILS, but removes the old references when the second file is loaded. The default is to not provide a second file.
