For each type of source in this guide, the general form and specific examples will be provided for both the Notes-Bibliography and the Author-Date style options of Turabian.
This information and several of the examples were drawn from A manual for writers of research papers, theses, and dissertations (9th edition). Numbers in parentheses refer to specific pages in the manual.
For further information, please ask your instructor or refer to the Turabian manual.
A Digital Object Identifier (DOI) is a unique alphanumeric string that is used to identify a certain source (typically journal articles).
If a DOI is listed on an electronic source it is included in the reference. When there is a choice between using a DOI or a URL, it is recommended that a DOI be used because they are more stable than most URLs.
Append the DOI to http://dx.doi.org/ in your citation. In addition, be sure to include that date you accessed the online source according to which style you are using: Bibliography style or Reference List style (p. 141).
For more information on DOIs and how they pertain to journal articles, check out pages 141, 148, and 220 of the Turabian Manual (9th ed.).
