Mangling of titles or forms of address
Sexual-shock-scene de jure
Modern opinions, speech, or behavior in the wrong era
Stupid nicknames or names no one had in that era
Overuse of cliches and stereotypes
Finding Grandma’s scrapbook, treasure trove of letters or diary
Tossing manuscript in the air and publishing in that order: i.e. too many timelines
Assuming because you read French that the whole world does too
No maps, family trees, of “cast of characters” at the beginning
