I have four bookcases of published diaries and memoirs scattered throughout the house, plus a few dozen on my kindle (it's easier to search for a specific word or topic or person electronically), so I have lots of sources to choose from. Although, admittedly, it was a lot easier to keep the different accounts straight in my head before I started on chemo. Chemo definitely makes you stupider. Word recall is a problem now, too.
The current work in progress has a chapter that posits that McElroy's regulators were actually a rival gang that took advantage of the attack on "Dowd" to eliminate the competition (the raiders), so I do use his accounts. I really felt like he just couldn't get let go of his 'we saved the whole prison from the raiders" narrative. He holds that the raiders were defeated once and for all with the hanging, and yet somehow they are still trying to "assassinate" Leroy Key and "Sargeant Goody" once they get to Millen.
This excursion into the question of the regulators aside, there are plenty of other sources available and why use one that you know is intentionally flawed?h
