Background

The Visible Human Project has its roots in a 1986 long-range planning effort of the National Library of Medicine (NLM). It foresaw a coming era where NLM's bibliographic and factual database services would be complemented by libraries of digital images, distributed over high speed computer networks and by high capacity physical media. Not surprisingly, it saw an increasing role for electronically represented images in clinical medicine and biomedical research. It encouraged the NLM to consider building and disseminating medical image libraries much the same way it acquires, indexes, and provides access to the biomedical literature. Early in 1989, under the direction of the Board of Regents, an ad hoc planning panel was convened and made the following recommendation: "NLM should undertake a first project building a digital image library of volumetric data representing a complete, normal adult male and female. This Visible Human Project will include digitized photographic images for cryosectioning, digital images derived from computerized tomography and digital magnetic resonance images of cadavers."

As one of the G7 Information Society Pilot Projects, the Global Interoperabilty for Broadband Networks (GIBN) is demonstrating high-speed networking on a global scale. The GIBN is currently coordinating a Trans-Pacific Digital Library Experiment (DLE). The DLE will use satellite and terrestrial high data-rate networks to demonstrate interactive digital library applications between collaborators in the United States and Japan.
