I am sure there must be dictionaries or websites catering to readers of specific much-published authors. Such as Dickens, for example. These lists would only contain words no longer common today, as these are the only words that need explaining.
But there are a lot of books published that call themselves "dictionary" or "concordance", even though they do NOT contain any vocabulary! So beware what you buy!
I only found one book so far that really seems to concern itself with vocabulary (albeit not in an academical but in an entertaining manner): https://www.amazon.co.uk/What-Dickens-Distinctly-Dickensian-Words/dp/0762460776/
