How do I find an article's DOI?
I need to include a article's DOI in my citation. Where should I look?
Depending on the citation style you're using, you may be asked to include a DOI when making reference to, or citing, a specific item. If the item was published prior to 2000, it may not have a DOI attached to it. However, all current digitally-available items have an associated DOI that will be included in the item's catalog record, as well as on the publication itself.
As an example, this is a journal article published in the online edition of the BMJ: British Medical Journal. The publication is available to us through ProQuest, and you can see the article's catalog record below. The DOI is listed at the top of the record (red box).
The DOI will also be listed in the article's publication details, which should be available in the catalog record as well (you may need to scroll down the record to find the DOI; red box).
If the DOI is hyperlinked, this will serve as the main access point for the article's existence online. Clicking the hyperlink will automatically redirect you to a webpage where the article is available online.
Finally, the DOI is also listed on the published copy of the article (both for physical and electronic items). This is typically printed at the top or bottom of the article's first page, and will be preceded by the acronym "DOI" (red box).
