Except when the library space is being used for meetings, the Mercer Library is staffed from 9 a.m. to 4:30 p.m. Tuesday and Thursday and 8:30 a.m. to 2 p.m. on Saturdays. To ensure access to the library, to locate holdings or to circulate items, it is best to contact the librarian to make an appointment.
The librarian is also the Diocese of Long Island archivist and registrar, and he should be contacted for inquiries relating to these roles.
