Robert S. (Bob) Engelmore, who retired in 1998 from the Knowledge Systems Laboratory at Stanford University, died in an ocean accident in Hawaii on March 25, 2003. As the second editor of AI Magazine, he guided its development from 1981 to 1991; he was also elected a fellow of AAAI in 1992. He had been involved in many aspects of AI and was respected for his uncommon common sense and good humor. He played football for Briarcliff Manor High School, learned to play the piano, and most importantly nurtured a deep interest in science. He won a nationally prestigious Westinghouse science scholarship to Carnegie Institute of Technology (later Carnegie Mellon University) and became a physics major.

This special issue celebrates the anniversary by presenting perspectives on AAAI's history, on the future of AAAI, and on the past and future of artificial intelligence. It highlights the many voices contributing to AAAI by featuring personal remembrances and visions from many people, including founders of AAAI, presidents who guided the society's development, and others spurring on AI research and applications. While a single issue can only scratch the surface, this special issue clearly illustrates the spirit, accomplishment, and optimism that will drive the next 25 years. It is fitting for AI Magazine to present such a commemoration: 2005 is the twenty-fifth anniversary of the magazine as well. From the beginning, AI Magazine has brought the AI community together to share ideas and advances and to introduce newcomers to the challenges and accomplishments of the field.

'm delighted to bring our readers the news of an exciting resource for AAAI members. AAAI has now completed a major initiative, begun five years ago, to develop a digital library of AAAI publications. The collection now comprises approximately 13,000 papers, including the full set of papers from the AAAI proceedings, papers from other major conferences, AAAI workshop and symposium technical reports, selected AAAI Press books, and the full contents of AI Magazine. This already-extensive collection is a growing resource, with new publications and access methods to be added over time. I encourage readers to visit it at the members' library section of the AAAI web site, www.aaai.org.

Carnegie Mellon University established a branch campus in Qatar in the fall of 2004. We are offering a BS degree in Computer Science to an international student body. The university invites applications for a visiting faculty position to begin as early as January 2006. We are seeking a faculty member in the area of Learning Science and Technology with research experience ideally in designing, implementing, deploying, and evaluating educational technology in school or college settings. An ability to teach courses in human-computer interaction, artificial intelligence, cognitive psychology, or related areas is also desired.

Robert Engelmore, a computer scientist and artificial intelligence pioneer, died March 25 during a family vacation in Kauai. He was a former executive director of the Knowledge Systems Laboratory who applied expert systems technology in scientific, industrial and military domains. Engelmore, 68, had been swimming in a rock-rimmed shoreline pool with his 5-year-old grandson, Jack, when they and other swimmers were overwhelmed by giant waves. Engelmore helped lift the child to safety but was pulled out to sea by currents. By the time lifeguards reached him, his heart had stopped beating.
