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.

Interactive computer-video modules for health sciences education.
Advances in electronic image recording and computer technology have resulted in a remarkable increase in the power and flexibility of interactive computer-video teaching systems. The University of Washington Health Science Videodisc Development Group first demonstrated a laser videodisc controlled by a remote central computer in 1980. Even this rudimentary unit highlighted basic medical informatics principles including: rapid accessibility; a "generic" or multi-purposed format; ease of computer control; and large collections of valid, rigorously reviewed images. Advances in medical informatics have led to the development of the following previously undescribed series of teaching units: 1. The hypertext programs Hypercard, Linkway, and Guide have been used with videodiscs to develop easy-to-use instructional and reference materials. These materials demonstrate the ease with which a computer-naive instructor may develop new programs and the advantages that the intuitive nature of these programs brings to student users. 2. Patient simulations using single and double screens plus pre-defined knowledge structures; 3. Interactive single topic tutorials using preset knowledge structures; 4. A key-word-based disc searching system; 5. Electronic video microscopy; 6. A series of programs developed independently by health science faculty who have purchased multi-purpose videodiscs that demonstrate the flexibility of the multi-purpose or "generic": collection concept.

The videodisc in health sciences education: a perspective on a powerful medium.
In the nine years since the introduction of the videodisc, biomedical communicators have created landmark applications of the technology. However, for a variety of reasons, the videodisc has not had the impact on health sciences instruction and communications that was initially projected. A sharp increase in numbers of microcomputers available in instructional settings and publicity regarding videodiscs has brought forth a burst of new interest in the medium and its relationship to information storage and retrieval. Although a number of newer technologies have been introduced, the videodisc remains the most cost-effective and proven technology for providing interactive visual information.
