Sierra has a non-MARC field in the patron record that is used by staff to communicate relevant, timely information to a patron within the context of their catalogue activity. This is a free text field. It used to display in Encore.

Why this is helpful for library?
1) we developed workflows that include this field
2) Messages could alert patrons to issues such as an expired card, account restrictions, required updates, or other actions they need to take.

Why is this helpful for the library user?
1) Messages can be targeted to a specific patron rather than displayed as a general announcement.
2) The message appears while they are searching, placing holds, or managing their account, when the information is most relevant.
3) Patrons can receive important information directly without needing to contact the library.
4) Important information doesn't have to rely solely on email, phone notices, or staff communication.
5) Patrons who do not regularly read email or receive notices through other channels can still encounter important information while using the catalogue.
