Long? yes. Respected, NO! not a chance. Passionate sage, american sphinxand founding brothers for starters should be reclassified as historical fiction because much of what ellis tells the reader is make believe. His books are worse than tabloid because he wraps them in the respect that most people ( many times wrongly) attribute to respected colleges. 

 what a hoax on the reader and the truth.   What is disappointing is that  
 those professors who could have spoken up did not they just kept quiet.   
 Notice that no scholars gie peer reviews on ellis that is because  
 they would put themselves in his catagory. What Winkipedia needs to do  
 ( if they are actually on the level and not in the pocket of the publishers 
 is to start a running list of historians who lie and allow others to  
 really tell the truth about these fictional history books)
