How to write a shortened version of a source in Chicago styles citing?

by Willjames97

Im not sure where to post this, sorry if this is the wrong sub.

I'm taking my first history class in college so far, my teacher says i need to use Chicago style citing instead of MLA.

On the footnotes, he says i need to use a shortened version of the source instead of the original if i use the source more than once.

Im only referencing one book and am completely lost and spent atleast 45 min. looking online for an answer. please help..

here's my citation and the comment he left on my first paper

citation: Demos, John. The heathen school: a story of hope and betrayal in the age of the early republic (New York: Vintage Books, a division of Random House LLC, 2014), 76.

comment: "You may use the short form for all notes after the 1st" "work on the notes themselves, after the first full note it's not necessary to repeat all that info again and again"

thanks

If you are citing the same source in a row, you can use the term “Ibid. Pg. Number”

So, for instance, I cite John Smith’s work once, then have to cite the same source a second time with no other source in between. I would use the full citation the first time, then ibid and the page number the second time. If I switch to another source, I have to use the full citation method. Here is a link that may help.
