Martha White has been a full-time writer and editor since 1987 and has a broad background in journalism, opinion columns, syndicated features, humor articles, book reviews, essays, and fiction. Her freelance articles have appeared in the New York Times, Boston Globe, The Christian Science Monitor, Country Journal, Down East, Early American Life, Family Circle, Garden Design, Yankee, and other publications. For many years, White worked as a contributing editor for Yankee Publishing and The Old Farmer's Almanac, also writing two weekly columns for the United Feature syndicate.

It has been White's special pleasure to become the literary executor for her grandfather, E. B. White. In 2006, she edited the revised and updated Letters of E. B. White (HarperCollins) and, since then, she has compiled two more collections of E. B. White's work: In the Words of E. B. White: Quotations from America's Most Companionable of Writers (Cornell University Press, 2011) and, most recently, E. B. White on Dogs (Tilbury House, Publishers, 2013).
