Searching for books used by Edwardian butlers in managing a household

[books and tweed]

I'm looking for the sorts of books a butler would read in Victorian or Edwardian England that would list proper procedures for serving, forms of address, rules of dress and tailoring for every time, place, and event, household duties, roles of the rest of the staff, inheritance rules, lists of peers and their families, etc - everything needed to run and maintain the Edwardian house and property. I'm sure much of this was passed on through training between butlers, but perhaps it was codified somewhere. Any leads would be appreciated!

Pretty sure butlers were illiterate.
