We are committed to providing the materials and services that satisfy the educational, informational, recreational, and cultural needs of our diverse community, and strive to encourage a lifelong interest in reading.
All library visitors over the age of 2 must wear face masks that cover the nose and mouth both inside a County library facility, and outside, when receiving library materials. See our Hybrid Opening Details for more information.
Public Browsing – Now open for longer
Quick, intentional visits instead of casual extended stays are encouraged. The Hollowbrook Branch will not be open for browsing, but is open for Curbside Pick-Up.
Appointments must be booked no later than one hour before the timeslot. If you would like to book a timeslot within an hour, please call the branch to see if they can accommodate you.
Mercer County Library Card holders have access to digital movies, music, magazines, books, articles, reference sources, business directories, and more – 24/7!
