The Elements of Style by Strunk & White was first published 50 years ago today and has sold over 10 million copies. E.B. White, famous author of Charlotte's Web, was a student of Cornell University Professor Strunk, who first put down his rules for writing in 1918 in a self-published "little Book" also named The Elements of Style. White revised and expanded it after Strunk's death -- so much of the book is really more like 90 years old today!
Isn't it amazing that this classic is still in wide use today? The books appeal is surely due to it's simplicity and call for brevity. One of the most important tenets is "Omit needless words". What else can I say?
