Originally published in 1989, much was known about blindness, but the field was divided into specialties. Experts in the different areas were widely dispersed among university departments, rehabilitation agencies, and school systems, with the result that people in one specialty area often knew little about developments in other areas. It was hoped that this work would be useful in reducing that isolation, by presenting, within a single volume, basic information derived from different approaches to the subject of blindness. Individuals already familiar with material in some of the chapters could gain added perspective on the field as a whole by reading about other aspects of blindness outside their specialty area.
