APA Citation Style is frequently used in the social sciences and natural/physical sciences. The first style rules were published in 1929 and the American Psychological Association has produced six editions of the Publication Manual since then.
APA style uses Parenthetical In-Text Citations within the main text of your paper. The sources that you refer to are then compiled into a References List at the end of the paper.
One key feature of APA style is that it now includes DOIs (Digital Object Identifiers), unique codes that are increasingly assigned to published articles.
Zotero is a robust tool for collecting, managing, and citing sources. It was built by George Mason University's Center for History & New Media. It is free and open source and tends to be a librarian favorite. Zotero functions as a browser plugin with a web backup. It works with Chrome, Safari, or Firefox, and integrates with Microsoft Word and Google Docs for in-text parenthetical/footnote citations.
Note: Tufts subscribes to Zotero Institution, which provides all members of the community unlimited individual and group cloud storage on zotero.org. To configure, simply add and confirm your Tufts email address in your zotero.org account. Contact a Tisch Librarian with any questions.
