Library PASS allows students in Cobb County to use their student ID number as a library card to access the Cobb County Public Library system's resources. Students can check out books, use computers and WiFi, and access online databases. To log into the online databases, students enter their 4-digit student ID number and a 4-digit PIN based on their birth month and date. All Cobb County school digital libraries provide a link to the Library PASS portal at www.cobbcat.org/librarypass.
