The Tract Association of Friends for nearly 150 years has been publishing and distributing books, leaflets and pamphlets in many different languages on the principles and doctrines of Friends. In this day and age there are few associations left which are dedicated to the one and only objective of publishing Truth. "A Key" of William Penn is again being offered not only because it is a clear and brief exposition of the original beliefs of Friends, but because it is a basic and fundamental presentation which is old yet forever new. As the twentieth century continues to unfold itself, the Tract Association of Friends trusts that it will continue in being given the responsibility of publishing Truth, so that the original and fundamental doctrines of the Society of Friends will not vanish from the earth.
