The box directly to the right details authoritative sources for information on APA Style. There are some web resources that have distilled information from those choices and make them available online. Note that there is NO complete APA Style Guide online.
These sources offer some style information:
The Owl at Purdue Purdue University
Provides a section "Research and Citation" that covers citation format information for the American Sociological Association (ASA) style, Chicago Manual of Style, MLA Handbook for Writers of Research Papers, Publication Manual of the American Psychological Association (APA).
The Rutgers University Libraries include the style manuals published by the APA. As of the most recent (2010) 6th edition, these manuals are only available in their entirety in paper format. To see Rutgers Libraries' holdings of the 5th edition and the new 6th edition (corrected second printing), please see the full title: Publication Manual of the American Psychological Association in the libraries catalog. Search under "Title Begins With."All of the Rutgers libraries should hold copies of these books. Some are in reference stacks, some not, most under call number BF76.
In 2007, a brief APA style guide to electronic formats was released in PDF format. It is available at: APA style guide to electronic references 2007 [PDF] Access from campus or login via Rutgers account. Please note that this short electronic style manual will likely be removed from our system soon since it is no longer current. Rutgers did not purchase the next edition of this short PDF, issued in 2012. The complete current authoritative information on APA style is only available in the APA Publication Manual...6th edition.

DOIs-now required by APA style
Use of DOI (Digital Object Identifier) is now preferred when using APA style. DOIs can be found on many articles, and in many indexing sources. If no DOI is available for an individual article, try searching "CrossRef" with the known article information (http://www.crossref.org.proxy.libraries.rutgers.edu/guestquery/ ).
All of the popular citation managers offer APA Style as a format. If you use a citation manager such as RefWorks, Zotero, or EndNote, you will see APA Style represented, and those tools will format the citations and produce bibliographies in the style. See the main tab on this guide labeled "Tools" for information on citation managers.
