REHABDATA, produced by the National Rehabilitation Information Center, is the leading literature database on disability and rehabilitation. The database describes over 80,000 documents covering physical, mental, and psychiatric disabilities, independent living, vocational rehabilitation, special education, assistive technology, law, employment, and other issues as they relate to people with disabilities. The collection spans 1956 to the present. REHABDATA results may also include abstracts from the international research collection, originally developed by CIRRIE. More than 120,000 documents are abstracted in this database. NARIC adds approximately 4,000 items to REHABDATA each year, including 1,000 international research documents.
