What books do you disagree with and why?

[LincolnMan]

After Betty told me about a book that should not be taken seriously, I decided to ask the learned members of this Forum as to what are the books pertaining to the Lincoln era that probably should be avoided or taken seriously. This is not meant to be critical of an author's work. We're not intentionally being mean. Perhaps the reasons for the selection as "book to avoid" should be stated. This could be very helpful to us all as we build our libraries and seek to learn the truth (as best we can). I mentioned that I own "Why Was Lincoln Murdered?" but have never read it. I have heard that it has "problems" to say the least. I suppose that the selections would also be chosen because of "standings" within the community of accepted Lincoln scholarship. Am I on track here?
