Automatic Renewals
Library patrons no longer have to remember to log into their account to renew the items they have checked out.
If an item has a renewal available, it will automatically renew on the due date.
An email notification will be sent on the due date alerting you that a renewal has been attempted for your items. Check the body of the email to find out whether your items were successfully renewed or if they were unable to be renewed.
Items will not renew under the following circumstances:
- if the maximum number of renewals has already been reached
- if you have fines/bills totaling more than $10 on your account
- if your account has expired
All CW MARS member libraries are participating in auto-renewal. This means that no matter which CW MARS library your materials are from, they will automatically renew on the due date if a renewal is available.
