The previous commentor notes how surprising it is that Randy Shiltz pulled all of this information together so quickly. It should be noted that he was a journalist with the San Francisco Chronicle (maybe the Examiner, I can't remember) who was covering this story from the early days. Many of the interviews that he uses to pull together the story were ones that he himself conducted at the time of the emergence of AIDS.
