The Lawrence Headquarters Branch is the main branch of the Mercer County Library System. We also have eight other branches, which are conveniently located to serve your needs. Access directions here; telephone numbers here; branch hours and holidays can be found here; and the monthly calendar of events for adults and children here. You can limit the calendar to a particular branch in the drop-down menu. All library patrons must abide by Library Policies.
Everyone is invited to use the Mercer County Library System. Please submit any requests for accommodation for people with disabilities to your local branch. V/TTY or NJ Relay 800-852-7899. Also, phone the NJ State Library Talking Book and Braille Center at 800-792-8322.
