Although the Online Writing Lab at Purdue University is a nationally-recognized reference for conventions of formatting and citation, as well as many other issues in writing, it has partnered with a for-profit company and now has ads and links to fee-based sites.

These books are the standards for style, format, and citation in their disciplines. Ask for them at the second-floor reference desk.

Immediately upon finding a possible source (article, book, webpage, or whatever), make a record of these four or five bibliographical elements, which are common to all styles and formats. Take notes, get a screenshot, check the book out, email the record to yourself, copy and paste the site URL, put it in a folder...if you can't describe the source, you cannot ethically or honestly use it. Later, when you have time, format the information according to a standard. "Citation Style Manuals" (left) lists styles most frequently assigned.
SOURCE (publisher, journal info, producer, website info, etc.)
DATE (location varies, but it's always required)
ELECTRONIC LOCATION (DOI, URL, name of database, etc.)
