William Penn Jones, Jr. (1914-1998) was a journalist and World War II veteran best known for his research into the assassination of John F. Kennedy. Jones wrote a series of books entitled Forgive My Grief and was editor-in-chief of The Continuing Inquiry, a newsletter focused on assassination theories. This collection contains a nearly complete run of The Continuing Inquiry and is full text-searchable.

In 1963, Penn Jones became involved in investigating the assassination of John F. Kennedy. A fellow researcher, Gary Mack, later explained, "Penn was one of the first generation of researchers who felt the government was behind the assassination - probably a conspiracy involving military intelligence... He always thought LBJ was behind it somehow." Jons was also the author of several books on the assassination: Forgive My Grief I-IV (1966-1976).

His photographs reflect his interest in the Kennedy assassination and his writing.  He published many of these photos in not only his books but his monthly newsletter, The Continuing Inquiry
