Frequently Asked Questions (FAQs)

Basic Library Information

  • How do I contact the Library?
    Go to our Contact Us Page for all our contact information.

  • What are the hours of operation for all of the Branches?
    Go to our Hours and Closings Page for all branch hours of operation.

  • How do I get a library card?
    If you do not have a library account with MCLS, but believe you are eligible for one, you have two options:
    1. Visit the closest branch to complete an application. To do so, you will need an ID, proof of residency, and children under the age of 14 need the permission of a parent or guardian. Go to Part 5 of our System Policies, Applying for a Library Card, for more detailed information.
    2. Submit an online request for a card. This will great you temporary access to all of our services, which will expire after three months. You will need to visit your home branch within that time to verify your library account information and show proof of eligibility. You will be given a physical library card and key tag barcode at that time. To register online, go to our Online Library Card Application.

  • Is the fines and fees schedule for MCLS available on your website?
    Yes. Go to Attachment A: Fines and Fees Schedule in our System Policies. This page includes information on the loan periods for each item.

Finding What You Need

  • How do I find out if the Library has something I want?
    The easiest way is to search our catalog, which you can do online on the MCLS Catalog Website or via BookMyne, a mobile application (BookMyne – App Store or BookMyne – Google Play). If you don't feel comfortable searching on your own, you can call the Reference Desk at any of our branches. The phone numbers can be found on our Contact Us Page. (Note: Our Reference Librarians can take only three searches/hold-requests per call.)

  • How do I use the online catalog?
    Go to the Catalog Help page for detailed instructions on how to use the MCLS Catalog Website.

  • How can I obtain a book that is not at the Mercer County Library?
    For newly published/released items, use our Suggest for Purchase Form as we prefer to purchase new items rather than loaning them from another library. For specialized, expensive, or older books that a typical bookstore or library does not have, use our Interlibrary Loan Request Form to request older items from libraries outside our system. If you don't feel comfortable submitting these forms on your own, you can call the Reference Desk at any of our branches. The phone numbers can be found on our Contact Us Page.

  • Where do I get eLibraryNJ help?
    For eLibraryNJ help, go to the OverDrive Help website.
