In our September/October issues, we examine the lasting effects of the September 11, 2001, attacks on libraries and librarians. The stories in this special report include: a look back at the 21 libraries destroyed in the World Trade Center and the documentation activities that followed this immense cultural loss; recollections from librarians who countered post–September 11 ignorance and bigotry with programs and information about Islam and the Middle East; a profile on the public library of Gander, Newfoundland—a small Canadian town that found itself in the spotlight when 6,500 travelers were diverted there after the attacks; an overview of two archives preserving the broadcasts and digital ephemera of September 11; and an interview about privacy and surveillance with the Connecticut Four, the four librarians who challenged the Patriot Act and government overreach that followed the attacks. Twenty years on, these accounts remain powerful and relevant, serving as a reminder of the profession’s role in telling and keeping our collective history.
