The Contra Costa County Library has contracted with Unique Management Services (UMS) to act as our materials recovery/billing agency to recover identified overdue materials and fines.  Accounts sent to UMS are assessed a $10.00 fee to cover the cost of doing business with the agency.

After 60 days past due, delinquent accounts with a balance of $35.00 or more (prior to July 1, 2015) or $50.00 or more (effective July 1, 2015), in fines and/or fees will be sent to UMS.

Those borrowers under 18 years of age will not be contacted directly.  All correspondence will be directed to the “parent or guardian of…."

When an account is sent to UMS, a note regarding the activation with UMS is automatically posted to the account and any borrower sent to UMS is blocked from checking out further materials. The account must be resolved and all items returned and/or paid in full before borrowing privileges are re-instated.  Once an account has been cleared the note regarding referral to UMS is automatically deleted from the account.

Payment plans may be set-up. 


The Library will notify you by email, phone or U.S. mail when holds are ready for pickup and when items are overdue.  The Library does not notify you if you owe fines unless you have items that are also overdue or lost; or your account has been referred to our materials recovery and billing service, Unique Management Services, in which case a $10.00 collection/service fee will be assessed to the account.

You will be provided with the due date at the time materials are borrowed.  You may also check your due dates and current account status online at, by calling 1-800-984-4636, or visiting your nearest community library.

Library Notices are provided as a courtesy.  Borrowers are responsible for returning materials on-time.

Overdue notifications are sent as follows:

  • 10 DAYS OVERDUE: Library sends overdue notice by e-mail or phone or U.S. mail

  • 30 DAYS OVERDUE: Overdue items are now set to Lost. Library sends a bill by U.S. mail for lost item

  • 60 DAYS OVERDUE: Account balances of 50.00 or more (effective July 1, 2015), or $35.00 or more ( prior to July 1, 2015), are sent to a materials recovery agency, Unique Management Services (UMS, aka Unique National Collections); and a $10.00 materials recovery fee is added to the library card account to cover that cost. UMS will attempt to contact the cardholder or their parent (if cardholder is a minor), both by phone and U.S. Mail. Accounts will remain in collections until overdue materials are returned and/or outstanding fines and fees are paid in full, and any remaining account delinquencies are otherwise resolved.
