It covers 16,000 observing sessions over 50 years. Given his active
background in variable star observing there may be many articles of
interest here for those interested in history of variable star
astronomy projects. For example, his discovery of the March 23 1990 TV
Cor outburst is noted in Volume 16. On page 26, for example, are his
historical observations of TV Cor made at the Harvard Plate Stacks.
