R. Stephen Berry is now James Franck Distinguished Service Professor Emeritus at the University of Chicago and is also special advisor to the director for national security at Argonne National Laboratory. He received his undergraduate and graduate education at Harvard, entering in 1948 and completing his doctorate in February 1956. He was an instructor at the University of Michigan and an assistant professor at Yale from 1960 until 1964, when he moved to the University of Chicago. He has been a member of its Chemistry Department, its James Franck Institute, the College, and the School of Public Policy Studies. His scientific activities have involved both experimental and theoretical studies. They have included studies in electronic structure of atoms and molecules, atomic and molecular collisions, chemical kinetics, chaos and regularity, atomic and molecular clusters, thermodynamics (especially of finite-time processes), and most recently, protein dynamics. His activities in areas of public policy have involved efficient use of energy and resources, science education at the middle and high school level, science and law, and of course the distribution of and access to scientific information.

Berry is married, with three children and seven grandchildren. He continues to enjoy skiing, hiking, and fly fishing, as well as music and photography.

Martin Blume is editor-in-chief of the American Physical Society, on leave from his position as senior physicist at Brookhaven National Laboratory. He received a B.A. from Princeton and a Ph.D. in theoretical solid-state physics from Harvard. At Brookhaven he has served as head of condensed matter theory, chairman of the National Synchrotron Light Source Department, and deputy director of the laboratory. He has also held a joint appointment as professor of physics at the State University of New York at Stony Brook. Since 1997 he has been editor-in-chief of the American Physical Society, with responsibility for all of the Physical Review journals, Physical Review Letters, and Reviews of Modern Physics. The challenge of electronic publishing and associated questions of intellectual property, archiving, peer review, cost containment and recovery, and provision of journals to all who need them are among those that must be addressed in this time of change in scholarly communication.

Charles P. Casey received his early education in St. Louis, Missouri (B.S. in chemistry, St. Louis University, 1963). His graduate research with George M. Whitesides at the Massachusetts Institute for Technology (MIT) was on organocopper compounds. After receiving his Ph.D. in 1967, he spent several months at Harvard University as a National Science Foundation (NSF) fellow in the laboratories of Paul D. Bartlett. In 1968, he joined the faculty at the University of Wisconsin-Madison where he is now Homer B. Adkins Professor of Chemistry and Steenbock Professor in the Physical Sciences. He was department chair at Wisconsin from 1998 to 2001. He was President of the American Chemical Society (ACS) in 2004.

Professor Casey's research focuses on mechanistic organometallic chemistry. The mechanisms of important catalytic processes including hydroformylation, hydrogenation, and alkene polymerization are being explored. His group has characterized d0 yttrium-alkyl-alkene complexes as models for the key intermediate in metallocene-catalyzed alkene polymerizations. Earlier work involved metal-carbene-alkene complexes and their role in both cyclo-propanation and olefin metathesis, chelating diphosphines with wide natural bite angles as effective ligands for highly regioselective hydroformylations, and heterobimetallic compounds. He is author of more than 250 papers in organometallic chemistry.

Dr. Casey is a member of the National Academy of Sciences and the American Academy of Arts and Sciences and a fellow of the American Association for the Advancement of Science. He has received the Alumni Merit Award from St. Louis University, an Alexander von Humboldt Senior Award, a fellowship from the Japan Society for the Promotion of Science, the Arthur C. Cope Scholar Award of the ACS, and the ACS Award in Organometallic Chemistry; he was a National Science Council Distinguished Lecturer in Taiwan.

While at Berkeley, he also taught musicology at Stanford University and began the complete revision of the definitive music research and reference materials, an annotated bibliography popularly known as Duckles in honor of its original compiler. Yale called him to the post of associate university librarian and director of collection development in 1986. In 1993, he joined the Stanford staff as the Ida M. Green Director of Libraries. In 1994, he was named to his current position of university librarian and director of academic information resources. In 1995, by establishing HighWire Press, he became its publisher, and in April 2000, he was assigned similar strategic duty for Stanford University Press.
