'I've said this before, but it bears saying again: the World History Chart is without a doubt one of the finest Web sites I have ever visited. I have the paper version (ordered a year or so ago) and continue to spend many happy hours poring over it. The Web site is a wonderful implementation of that wonderful tool.'

'I've purchased several of your charts in the past, and my discovery of this online project has been a real thrill. This is by far the coolest site on the web. Not only that, it is probably one of the most important. What a natural and fantastic use of technology to enable us to leap backward in time and expand our intellectual horizons.'

'Just received your chart and accompanying booklet of the World History Chart. I am pleased with the printed product, as I am fascinated with any graphic which can show at a glance the timeline of recorded history. I find it especially useful in teaching my military history courses to US Army officers.'

'May I offer my congratulations on a truly excellent presentation. It isn't often that one finds significant merit on this network anymore, and I consider myself fortunate to have found your site. As an historian and general systems scientist by training, it has often seemed that there should be some way to portray the broad temporal event relationships in such a way that we could understand the relationships . . . .
