Many books deal exhaustively with the eyewitnesses, the photographic evidence, Oswald's background, or the medical evidence (but seldom more than one or two of these at the same time), while those that are comprehensive tend to rely heavily on previous publications. In other words, the field is so vast these days that if you want to investigate you have to specialize, and if you want to be comprehensive you won't have time to do much more than rearrange the previous literature. Summers is the exception to this rule.
The 1981 edition went into NameBase first, and then updated portions
from the 1989 edition were added. There is also a 1991 edition that we
don't have. In it Summers wrote a foreword that criticized Oliver Stone
even before his movie had been released, proving once again that
assassination researchers are their own worst enemies.
