    The Mercer Island School District has partnered with the King County Library System (KCLS) to increase student access to KCLS’ online resources.

    KCLS has created special library accounts in its system for all students in our district so they may seamlessly log in from school, home or from any computer or device.

    The account numbers are formatted as the student’s school ID number preceded by the Mercer Island School District’s three digit number (400).

    For information about access different services, please use the links on the left.
