A good place to begin

Dr. Treffert's book, Extraordinary People: Understanding Savant Syndrome, was the first work to comprehensively summarize what is known about this fascinating condition, originally described a century ago, and to introduce the reader to a number of prodigious savants.

 His more recent work, Islands of Genius: The Bountiful Mind of the Autistic, Acquired and Sudden Savant not only brings the reader up-to-date on developments in the field, but also presents the fascinating stories of the savants as well as their caregivers and  families. Preview Islands of Genius.

Both of the above works are on our shelves, and we encourage our visitors to make full use of these comprehensive resources.
