Step 6.1: Authority Update Frequency


The frequency of running Notification Services for your library should be based on the following:

  • Frequency - How often does your organization’s authority file need to be updated?
  • Resources - Does your organization have the staff to upload changed authority records at the frequency you chose?
  • Cost - Is frequency important enough to incur additional cost? (weekly and monthly delivery are more expensive)

Most libraries under 500,000 bib records do not need to run Notification Services more than four times a year. A good way to measure how frequent you need this service done is to compare it to how often you add bibliographic records.

If you are adding about 5,000 records a quarter then both Current Cataloging and Notification Services should be run every quarter. If you are adding about 5,000 records once a year then consider running Notification and Current Cataloging Services once a year.

You can then establish a start date to begin the Notification Service. The start date can be selected based on local needs.

If a library has chosen quarterly Authority Updates, and has selected to begin the updates in April, the updates will run in April, July, October, January. Both the frequency and schedule can be changed upon request.

Please check with your MARS 2.0 project manager to determine an efficient Notification cycle for your organization.
