A Polybiography is the use of archived internet email services such as ListServs and WWWeb to publish historical information by those involved in the history. The historical web site and ListServ provide for formal historical articles, images, photographs, commentary, and discussion of those items in a process called a "polybiography"... the history by many of the many events. The site is designed to be a searchable repository of "raw material" for those with an interest in the history of Diagnostic Medical Sonography (ultrasonography).
