After reading Lincoln's First Inaugural Address and realizing Lincoln's firm determination to honor the oath that he had taken to "protect and defend" the Constitution of the United States and the Union, the author developed a compelling desire for information pertaining to his assassination. He spent over fourteen years searching the shelves of used-book stores and libraries in the Washington D.C area, including the Library of Congress, for pertinent, fact-based material; accumulating over sixty sources. "The True History of Lincoln's Assassination" is accurate, all-inclusive, and has been reviewed by The Abraham Lincoln Research Library whose assessment is that "... it is very well researched and provides a variety of perspectives that researchers may utilize." It contains many photographs including several that have never before published.
