I'm not sure if anyone else has brought this up yet, but the periodicals page on the Google Books website is now featuring a very extensive archive of Black Belt magazine.

Some people here might remember that in 2003, Black Belt magazine named Dr. Yang the Kung Fu Artist of the Year. The January 2012 issue ran an excellent article on Dr. Yang's ten-year training program in California. I actually believe the YMAA site has a landing page for Black Belt readers.
