The New York Civil Liberties Union (NYCLU) is the preeminent statewide organization dedicated to the protection and enhancement of individual civil liberties and civil rights in New York State. Founded in 1951, the NYCLU's mission is to defend and uphold the basic rights and liberties articulated in the Bill of Rights and to advocate, litigate and educate for the protection of civil liberties. Through litigation, legal counsel, advocacy and legislative lobbying, the NYCLU has, among many issues, protected political freedom during the McCarthy era, argued against the constitutionality of the Vietnam War, created the first project focused on the rights of mentally disabled, and was the first civil liberties organization to advocate for reforming the foster care placement system. Over the last thirty years, the NYCLU has advocated for issues surrounding voting rights and censorship, fought to end gender discrimination and school segregation in New York State schools, and defended the separation of church and state. The collection consists of legal case files, administrative records and other archival materials. The collection is being processed and is currently closed, unless permission to access is granted in writing from the NYCLU Executive Director.
