The resources in this guide are useful for exploring the ideas of other writers, and building upon them. Be sure to give credit to the original author when quoting from these or other works, or using the ideas found within them. Good citations should clearly spell out the sources you have used, and make it easy for readers of your paper to track down the works you have consulted. For guidance on constructing references, you may consult one of the following style manuals. (If you are writing for publication, find out what style is adhered to by your publisher. If this is for a class, ask your instructor which style manual is preferred.) For each of the style manuals listed below, the print version (located at the D. H. Hill Library Reference Desk), provides the most complete information about writing, plagiarism, and citing sources in a wide variety of formats. The versions on the web provide quick guidance on constucting references to electronic sources.
