When you cite your sources, whether they are books, journal articles, a web site, speeches, television transcripts, etc., you will be expected to use a specific format with regard to order and punctuation. There are a number of style manuals, but most literary papers will tend to follow the Modern Language Association's recommended style. A copy of the MLA handbook for writers of research papers is kept at the Reference Desk. An electronic version is available on the web from Purdue University's Online Writing Lab (OWL).
For Citing Images in your papers, presentations, handouts, etc., please see the Libraries' Citing Images Guide.
