I’ve written hundreds of articles, 403 at last count, with a handful more since then. Almost all for print media. Therefore, my online professional links are a small fraction of my CV. Below are the results of an ego search to see what I could find of my commercial writing on the Internet.

You have to sign up for an account to read them. “Katherine Walcott is a freelance writer living in the countryside near Birmingham, Al. She writes for anyone she can talk into paying her and rides whatever disciplines she can talk her horses into doing.”
The Bloodhorse: Girth Tightness and Performance, Deirdre B. Biles, March 20, 2001. “A girth that is too tight can have a negative effect on a racehorse’s performance. That conclusion is based on recent research conducted in Australia, writes Katherine Walcott in the April edition of The Horse.” Summary of article.
