of the Overview, and could not have done so without the commitment of OPCL's dedicated staff. OPCL would particularly like to recognize: the written and editorial contributions of OPCL Senior Counsel Alex Wood, who carefully shepherded the publication of this edition from beginning to end; the written and editorial assistance of its volunteer interns Yasmin Emrani, Meryl Kanofsky, Kaiya Lyons, Craig Wesoly, Hannah Mayer, Danielle Prongay, and Kelly Singleton; the management of the publication process by its program specialist Pamela A. Moye; and last, but certainly not least, the invaluable written and editorial contributions of its former Director, Joo Y. Chung, who led this edition to completion before her departure from the Department of Justice. This 2015 edition of the Overview is specifically dedicated to her. Without the valuable assistance of these individuals, the completion of this endeavor would not have been possible. Kristi Lane Scott Acting Director Office of Privacy and Civil Liberties.
