Most of the library's databases provide you with the option to generate citations for resources. This option as well as printing, saving, sharing, and other tools are often listed along the right side. If not there, scroll to the bottom of the webpage to see it is there.
If you need to select a citation style and an edition, use the most current edition (e.g. APA 6th edition, MLA 7th edition). Consult your syllabus or ask your professor if you should use an older edition.
Warning! Double check the accuracy of the citations. Information may be missing from the citation. Punctuation and capitalization may be incorrect. However, the generated citation gives you a start of writing the citation rather than beginning from scratch.
