Here is some guidance
APA: psychology, education, and other social sciences.
MLA: literature, arts, and humanities.
AMA: medicine, health, and biological sciences.
Turabian: designed for college students to use with all subjects.
Chicago: used with all subjects in the "real world" by books, magazines, newspapers, and other non-scholarly publications.
It is ethically imperative to always cite sources correctly and thoroughly in order to credit the original records creators and to lead other scholars to the materials. Proper citation should lead your readers directly and unambiguously to the sources you have consulted.

Abbott, Edith, "Excerpts of Address at National Women's Trade Union League Nebraska," 1934. Abbott, Edith and Grace. Papers, [Box 24, Folder 13], Special Collections Research Center, University of Chicago Library.
This citation leads a reader directly back to the original source.
