Citation management tools help you manage your research, collect and cite sources, and create bibliographies in a variety of citation styles. Each one has its strengths and weaknesses, but any are easier than doing it by hand!
Zotero: A free plug-in that works exclusively with the Firefox browser: keeps copies of what you find on the web, permits tagging, notation, full text searching of your library of resources, works with Word, and has a free web backup service.
RefWorks - free for UC Berkeley users. It allows you to create your own database by importing references and using them for footnotes and bibliographies. Use the RefWorks New User Form to sign up.
It's always good to double check the formatting -- sometimes the software doesn't get it quite right.
Citation Help
"Ethics, copyright laws, and courtesy to readers require authors to identify the sources of direct quotations and of any facts or opinions not generally known or easily checked."--
Chicago Manual of Style, 15th edition (Chicago: Chicago Univ. Press), p. 594
Why cite sources? Whenever you quote or base your ideas on another person's work, you must document the source you used. Even when you do not quote directly from another work, if reading that source contributed to the ideas presented in your paper, you must give the authors proper credit.
Citations allow readers to locate and further explore the sources you consulted, show the depth and scope of your research, and give credit to authors for their ideas. Citations provide evidence for your arguments and add credibility to your work by demonstrating that you have sought out and considered a variety of resources. In written academic work, citing sources is standard practice and shows that you are responding to this person, agreeing with that person, and adding something of your own. Think of documenting your sources as providing a trail for your reader to follow to see the research you performed and discover what led you to your original contribution.
How do you cite sources? The means to identify sources is to provide citations within your text linking appropriate passages to relevant resources consulted or quoted. This can be done through in-text parenthetic notes, footnotes, or endnotes. In addition, a bibliography or list of works cited, is almost always placed at the end of your paper. The citation system and format you use will be determined by the citation style you choose.
Below are links to guides for the three major styles used for most academic papers or research in the humanities, social sciences, and some scientific disciplines:
APA Style Guide (Purdue) - From the American Psychological Association. Often preferred in the fields of psychology and many other social sciences.
MLA Style Guide (Purdue) - From the Modern Language Association of America. Often preferred in the fields of literature, arts, humanities, and in some other disciplines.
Turabian & Chicago Styles Guide - From the work of Kate Turabian at the University of Chicago and the University of Chicago Press. Often preferred in history and many other disciplines.
How do you choose a style? Ask your instructor which style sheet he or she wishes you to use and if there are other special formatting instructions you should follow.
