On Oct. 13, 2023, Brooklyn Law School hosted the event: Civil Liberties: The Next Hundred Years.  This was a panel discussion featuring BLS Professor Susan N. Herman (former President of the American Civil Liberties Union from 2008 to 2021) and other civil libertarians.

  • This year, Professor Herman published the book: Advanced Introduction to US Civil Liberties (Edward Elgar Publishing, 2023).  This book is available in both the circulating Main collection and in the first-floor Course Reserve collection.
    • Publisher's description of this book: “This insightful Advanced Introduction provides a kaleidoscopic overview of key US civil liberties, including freedom of speech, press, assembly, and religion, limitations on search and seizure, due process in criminal proceedings, autonomy rights, rights of equality, and democratic participation.”
