If you don't use a citation manager, you're working waaay too hard. It's a very easy and convenient way to store and format all of your references-- books, journal articles, websites, etc. The Library has made RefWorks is available to everyone at UMass, for the entire time you're here. It's a web-based citation manager, so you can access your bibliographies from your room or your office, or Baltimore or Barcelona. Formatting options for the most commonly used styles in academia are included. There's even a Write-n-Cite feature, which allows you to insert a placeholder for a reference into your paper as you're writing, and formats the in-text references as well as your bibliography.
