A Note About Membership:

Thank you for your continued support and patience with us as we navigate transitions in the development department, including staffing changes. These changes have led to delays in sending membership renewal reminders and processing membership renewals.

Please be assured that during this time of transition, your membership will be honored even if you have not yet received your renewal packet.

We are working tirelessly to process renewals and reminders, and we anticipate having the open position filled in the coming weeks.

In the meantime, if you have any questions regarding the status of your membership, please contact

Thank you very much for your patience as we navigate this transition.


The Research Library of the Mercer Museum houses over 20,000 books, 2500 feet of county archives, over 12,000 images and more!
