Find, reserve, and renew library materials with the click of a mouse…


  • The classic catalog, ALIScat indexes materials from participating Nassau county libraries.  Unfortunately, this version of the online catalog is no longer supported by our software vendor.  We encourage you to use the enhanced catalog, Encore.

  • An enhanced catalog, Encore enables patrons to refine search results at a glance by availability, location, language, format and more.

  • A feature of both the classic ALIScat and Encore catalogs, LI LINK enables patrons to search and request materials from libraries county wide through a cooperative between participating Nassau and Suffolk libraries.
  • For materials not available in the Nassau or Suffolk County library system catalogs, a Reference Librarian can perform an extended search to find the item outside of our System.

Manage your library account…

Use the online catalog to manage your library membership account.

The first time you click on My Account, you will be asked to enter your name, library barcode (on the back of your library card) and a personal identification number (PIN) that you create yourself. (We do not assign it.) You will need to re-enter this basic information every time you access your account again. This is not the same pin used on our public computers.

Here are some of the things you can do with your personal account:

  • Check the status of your materials to verify when they are due
  • Renew or request materials from Nassau County and Suffolk County
  • Change your PIN, phone number, or email address
  • View your fines (Please note: At this time you are unable to pay your fines online)
  • Opt-in to view your reading history (Only items checked out after you opt-in will be available to view)

If you add your email address and cellphone number to your account information, you will have the option to receive courtesy notices by email or text message. Courtesy notices will alert you when materials are about to come due, or requested items have arrived. You will also be able to reset your PIN if you forget it. If you have questions or need help, please call the Reference Desk (516) 481-6591 x21 or x22 or email
