The book Chaiye Moharan [the life of Rav Nahman] was not edited. You can see this in a few places. One that come to mind is the statement that Columbus died in chains. This is brought as a proof that who so ever brings some great thing into the world suffers for it. While there are plenty of proofs plus the verse "one who increases knowledge increases pain], still Columbus did not die in chains. He was put into chain in the New World by a favorite of the court, and sent back to Spain in chains. They were removed by Isabella and Ferdinand immediately when he arrived. As far as we know they were buried with him when he died as he cherished them as a symbol of his loyalty to his monarchs.
But it also should be noted that he was extremely dishonored and died poor. [But he still had credit he could draw on to pay his rent at an inn.]
There are five major books from Rav Nahman. The most well edited are LeM, Midot, and Stories. The Conversations and Life of Rav Nahman were put together from the writings of Rav Natan. But the publishing took on a series of sad events. It was not edited by Rav Natan, and tons were left out. Later, Rav Shmuel Horwitz's "Left out Parts" helped make up some of the lack.
[But of all the books of Rav Nahman, the Conversations and the Life are the most instructive for me. I mean the path of learning in Conversation 76 you see only in the Conversations and only slight hints of that in the LeM itself.
