As a graduate instructor for technology courseware I was please to find such a good resource for the history of the computer industry. This is a great resource for those in the industry who wish to learn more about the early evolution of computers. It also captures the length that our society has used computers and puts a framework around what people "think" is a 10 - 20 year old industry. It definately should be a part of anyone's library who has a role in the computer industry and wishes to understand the past and how it relates to the future.
