A survey of videodisc and interactive videodisc projects in North America: Part I.

Selected videodisc (VD) and interactive videodisc (IVD) programs, projects and topics are presented in two articles in this and a subsequent issue of the journal. Part I reviews the impact of Information Science developments on image management. The American Society of Hematology Slide Bank and other specific applications in urology, paediatric neurology, obstetrical nursing, medical decision making, dental diagnosis and treatment (DDT), and paediatric cardiology, are reviewed as educational and informatics research projects. This is followed by a section on three-dimensional reconstructions of the brain which stresses digital images. Multi-purposing and repurposing are reviewed in two prototype programs. A discussion of the multidisciplinary Slice of Life projects completes this first article.
