The New Yorker has an article up that focuses on his work and links to a number of his writings.
And Jimi Izrael has a post up at The Root entitled "The Education of Dr. Henry Louis Gates Jr." A quote:
The arrest of Harvard Professor Henry Louis "Skip" Gates Jr., at a minimum, quashes any talk of a post-racial America. It may not be the best example of racial injustice I've ever seen, but it's a great example of how life for black people is often complicated by class and race. If a mild-mannered, bespectacled Ivy League professor who walks with a cane can be pulled from his own home and arrested on a minor charge, the rest of us don't stand a chance.
We all fit a description. We are all suspects.
