The Center for Technology in Government (CTG), through the Using Information in Government (UIG) Program, has worked for more than a year with New York State agency project teams and partners from the public, private, and academic sectors to identify benefits and strategies for integrating and using information for program planning, evaluation, and decision making. The policy, management, and technology issues identified through our work with the agency teams were shared with the public in a series of seminars focused on increasing the value of existing information to government programs. This report summarizes the presentations given at the third session of the Using Information in Government Seminar Series, "What Rules Govern the Use of Information?" which was held on October 5, 1999 at the University at Albany.
