In 1900, New Jersey Senator William M. Johnson began a rich legacy of giving when he donated land and funded the construction of the library in Hackensack. Since opening in 1901, the Johnson Public Library has been a vital resource to the people, schools, medical institutions, legal offices, and organizations of Hackensack and the surrounding communities. As a thriving and evolving public library, it has given countless adults and children opportunities and avenues to learn and grow.
