I received the Aug-Sept 2009 issue of ATTRA News, which is the "Newsletter of the National Sustainable Agriculture Information Service: A project of the national Center for Appropriate Technology (NCAT)" the other day.
This month's issue is dedicated to "Pasture-Based Beef and Dairy Production", ie it's talking about Grass-fed beef.
ATTRA News is intended to educate farmers and other interested persons about sustainable agriculture. This issue includes an article about grass-fed labeling and another comparing the various standards for meat production of grassfed beef.
It turns out there are three standards that apply to grassfed beef: the USDA Agricultural Marketing Service Grass Fed label, the American Grassfed Association's American Grassfed label, and the USDA National Organic Program.
These differ considerably and if you are a consumer interested in grass fed beef, you might want to check this article out before you decide what to buy.

The newsletter also has extensive resource lists about cattle raising (aimed at farmers and ranchers, of course).
