Q. Are there any sites or software that can help with creating citations and works cited?
There are quite a few sites that can aid the user in creating citations and works cited, though none are fool-proof and they cannot act as a substitute for a basic understanding of the rules of the specific format one is working with.
For an excellent overview of MLA, APA, and Chicago styles, plus sample papers written in those formats, see the OWL Purdue website: http://owl.english.purdue.edu/owl/section/2/
Son of Citation Machine ( http://citationmachine.net/index2.php ) creates citations for MLA, APA, Chicago, and Turabian.
NoodleTools ( http://www.noodletools.com/ ) is an alternative to Son of Citation Machine; choose the NoodleBibExpress option for the free version.
Many databases have the ability to instantly create the citation for the article, video, or other information you are looking at, in a variety of styles. Often the button for this is along the top or the side.
