Options for Searching for a Patron’s Record

Click on Check-Out (Circulation Desk) from the dropdown menu in the upper right corner of the Sierra program.

There are several options to bring up the patron’s record.  

  • Scan the patron's barcode.  Type in the patron’s barcode number as well.

  • Type the letter “n” and the patron’s last name and first name. Typing the letter “n” helps Sierra understand what index you want to search.   

Since Sierra is a shared system with all Marmot members, you may find a patron with the same name at multiple locations.

Note: If your display does not look the same, you can contact Marmot to make changes to your Sierra login.


If you accidentally click on the patron for the wrong location, the system will give you a message that the patron is not registered at this location. You would need to do the search again and click on the patron for your library.

Search by Patron Birth Date

  • Search by the w  BIRTH DATE

    • The birth date is not something that can easily be searched. The birth date in this index search is associated with the variable fields in the patron record. 

Normally, the birth date is listed in the fixed field of a patron record. However, the Birth Date index is based on the patron variable field.

In order to be able to search the patron’s birth date, this information would need to be added to the variable field of the patron record. You would need to edit the patron’s record to insert the variable birth date field.

The patron number can be viewed in the patron's record to make sure it is the correct patron. Click on the View icon located under the FUNCTION Check Out (Circulation Desk)

A box will pop up with View Patron Record. The patron number is displayed in two places.
