Public Library

All residents, property owners, and visitors to the Mercer area are welcome to apply for a Merlin card from the Mercer Public Library. Your card is good at nearly 30 libraries in the Northern Waters Library System. You will be asked to fill out a simple application form, and children under the age of 14 are required to have a parent/guardian signature on their application form.

Download a Card Application Form (PDF) - Print and fill out this application form, and bring it to the Mercer Library to get your very own Merlin card! 

The library will serve all customers who request service.  Service will not be denied or abridged because of religious, racial, social, economic, or political status; or because of mental, emotional, or physical condition; age; or sexual orientation.
