None of these are true biographies anyway. These are “hagiographies” where no unflattering information is published about the person.
Artscroll has been known to exclude information that they deem either irrelevant or contrary to what they consider the “gadlus” of the person. They get away with this by claiming that “these are not meant to be a historical account, but rather to inspire the reader.” I guess that’s what passes as emmess these days.
Only person who published a book that could be considered a real biography got his book banned.
