THE HISTORY OF THE CHILD PORNOGRAPHY GUIDELINES
"This report provides a history of the child pornography guidelines. The child pornography guidelines have existed since their initial promulgation in 1987, and they have been substantively amended nine times. These revisions were prompted by, among other things, statutory changes, the United States Sentencing Commission’s independent analysis, and public comment. This report is the first step in an ongoing examination of the child pornography guidelines."
