"Assassination Broadsides"?

[Dave Taylor]

On the back of my 1990 reprinted copy of George S. Bryan's, The Great American Myth, there is a list of future releases by the publisher. One book listed here is Assassination Broadsides: An Annotated Guide by James Swanson.



Does this book exist? A Google search for it came up with nothing. I'm wondering if this planned book is what turned into Swanson and Weinberg's Lincoln's Assassins.
