Here is an interesting article about Ray Cook:

“The Language of Dance, Examined“, by Dana Gavin (Hudson Valley News, December 22-28, 2010, pp10-11.)

The article includes terrific photos of Laban and Labanotation.

Unfortunately, the link above is a little hard to navigate and view, at least on my computer. You need to go to the site, then click on the picture of the newspaper, then click on the thumbnail at the bottom for pages 10-11. To enlarge the view see the icons at the top of the page.
