How to cite an old poem which appears in a new collection/anthology put together by a different editor? (Chicago)
If the publisher gives you the option of using BibTeX, here are the BibTeX database entries I've used in an equivalent situation:

@INCOLLECTION{Newton:1726:PNP, crossref=&quot;Motte:1846:NPM&quot;,
author=&quot;Isaac Newton&quot;, title=&quot;Philosophiae Naturalis Principia
Mathematica&quot;, pages=&quot;73--507&quot;, edition=&quot;Third&quot;, year=1726,
note=&quot;Translated into {E}nglish by {A}ndrew {M}otte; first edition
published 1687&quot;,
url=&quot;https://archive.org/details/newtonspmathema00newtrich&quot; }
@BOOK{Motte:1846:NPM, editor=&quot;Andrew Motte&quot;, title=&quot;{N}EWTON'S
PRINCIPIA: THE MATHEMATICAL PRINCIPLES OF NATURAL PHILOSOPHY&quot;,
booktitle=&quot;{N}EWTON'S PRINCIPIA: THE MATHEMATICAL PRINCIPLES OF
NATURAL PHILOSOPHY&quot;, publisher=&quot;Daniel Adee&quot;, year=1846,
edition=&quot;FIRST {A}MERICAN&quot;, address=&quot;New York&quot;,
url=&quot;https://archive.org/details/newtonspmathema00newtrich&quot; }

Then you can let the publisher's BibTeX style file sort out the CMS formatting.
