Summary: With the advent of electronic communications technology, experts can share information within minutes. What are the consequences when more bits of scientific data cross more national borders and do it more swiftly than ever before? Bits of Power assesses the state of international exchange of data in the natural sciences, identifying strengths, weaknesses, and challenges. The committee makes recommendations about access to scientific data derived from public funding. The volume examines: • Trends in the electronic transfer and management of scientific data. • Pressure toward commercialization of scientific data, including the economic aspects of government dissemination of the data. • The implications of proposed changes to intellectual property laws and the role of scientists in shaping legislative and legal solutions. • Improving access to scientific data by and from the developing world.
