Most written accounts are fairly short, and many attribute behaviors or alter personalities to a form of religious possession, or link mental illness with belief in demons.
However some longer accounts were published by “physicians” and some historians found other accounts.
Many ordinary people couldn’t read and books were expensive rather than today’s mass-produced paperbacks and ebooks about DID.
