I purchased this set of encyclopedias myself a year or so ago. I paid
$45 for the set in excellent+ condition. As far as the value as a
source, I guess it would somewhat depend on the individual. It's kinda
an updated version of the older classic set entitled, Complete
Photographer. It fact it has many of the same articles and
illustrations. I just happen to like older books on photography in
general and felt the set is something that I should have. My wife would
probably not agree with the need factor, however!
Cheers,
