It’s the same problem I faced as I began to gather material for my little Austen gift book.
There’s no point in quoting Jane Austen unless the reader is alerted about who spoke those words -- a deceiver, a heroine, a rattlebrain, or perhaps the narrator herself – and even then, her tongue is often quietly in cheek. I ended up writing a short note for almost every quotation. With "It is better to know as little as possible of the defects of the person with whom you are to pass your life”
I felt the need to explain that it came from“
"I declare after all there is no enjoyment like reading!" Yes, it comes from Pride and Prejudice. Where it is spoken by two-faced Caroline Bingley, who obviously cares nothing for reading and is simply angling for attention from aloof millionaire Fitzwilliam Darcy.
I could have warned the Bank of England.
