This is a wonderful resource for anyone with interest in the show!!
Love Is All Around

This book is all about The Mary Tyler Moore Show. While Ted Knight is obviously not the focus of the book, there are a number of references to him in the book including a section about his character. Even so, it's worth the read if for no other reason than to have a better understanding about the workings of the show that he helped to make so popular.
