Fan-1967 - She is cited in the Big Book, in her section. I would not call Tracy a professional author, thus it is not shocking that a web-search found no other books. I will find some source that is able to confirm the page. I think the page would also be beneficial to many of the AA community looking for any questions they may have had about the author. I am also in the process of finding more information on Tracy to add in the future. 
Thank You!
