I find that it's easier to locate old posts by searching Google rather than using Typepad's internal search function. Today I was searching for a post and didn't realize that I was searching Google Books.
I learned that this blog has been referenced in a few books. For example, Encyclopedia of Attention Deficit Hyperactivity Disorders, Evelyn B. Kelly, Greenwood Publishing, cites this post on sugar and ADHD. Funny thing is I don't even remember posting this, though I remember the research findings.
I'm not surprised when I see Dr X cited in Wikipedia, but I had never considered that someone would cite my blog in a "real" book from a real publisher.
