Many citation styles have begun using Digital Object Identifiers at the end of the citation - when available.
DOIs are unique codes that identify an electronic document, much like a social security number identifies a person. Additionally, DOIs can be used to find the document on the internet - usually at the publisher's web site.
For more information on DOIs, check out our DOI page.
