What is The Chicago Manual of Style?

The Chicago Manual of Style is a method of documenting one's books, journal aticles etc. It contains two basic documentation systems:

(1) Notes and Bibliography

(2) Author-Date

Selecting which one generally depends on the disciplinary area and the nature of the sources cited. Each documentation system tends to be used by scholars/students in different subject areas:   

1) The notes and bibliography style is preferred by many in the humanities, including those in literature, history, and the arts. This style presents bibliographic information in notes and a bibliography.

2) The author-date system is often used by those in the physical, natural, and social sciences. In this system, sources are briefly cited in the text, usually in parentheses, by author’s last name and date of publication. The short citations are amplified in a list of references, where full bibliographic information is provided.

Aside from the use of notes versus parenthetical references in the text, the two systems share a similar style.
