Query: This book is not a balanced treatment of the subject

The book is not a balanced treatment of Lincoln's place in American history.If you want to find out everything negative about Abraham Lincoln, this book is the place to look. However,it is not a balanced treatment of the subject and you will find almost nothing that conflicts with the author's viewpoint, even though there is substantial contradictory information available. For instance it faults Lincoln for not arranging for gradual emancipation of slaves but does not give him credit for the tremendous effort that he made for compensated emancipation. This omission is astonishing, because some of Lincoln's most famous quotes come from his congressional message in support of compensated emancipation. Overall the book is just a rant. It is not a scholarly contribution to the works on Lincoln.
