Is there a way to cite author of quotes?

Question

I am trying to implement a quote in my text, but the quote has a different author than the author of the book. Can I simply cite the book, and not the original author? Is it a way to cite the "correct" author in a quote, without adding to bibliography?

Answer 1

My suggestion is to attribute the quote to the original author, but mark it as quoted in or cited in whatever source you consulted. biblatex includes the quotedin string for this purpose.

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{packer:1991,
  author = {Packer, J. I.},
  title = {Among God's Giants},
  subtitle = {The Puritan Vision of the Christian Life},
  location = {Eastbourne},
  publisher = {Kingsway},
  date = {1991}
}
\end{filecontents}
\usepackage[australian]{babel}
\usepackage{csquotes}
\usepackage[style=verbose]{biblatex}
\addbibresource{\jobname.bib}
\SetCiteCommand{\autocite}
\begin{document}
  \null\vfill
  Richard Baxter writes

  for you to think on, and to provide for, it will be too high for you ever to
