Zotero and Zotero Bib
In your time at Harvard, you'll hear more than one librarian suggest that you use Zotero, a "citation management tool." Zotero will be great for big projects that require you to keep track of many sources -- like junior tutorials and senior theses (if you end up writing one.
In the meantime,we recommend you generate citations with ZoteroBib
It's more reliable than the internal HOLLIS citation generator and you don't need an account or special software to use it. Some of its handy features are described on this page.
Next semester, or next year, you might want to graduate into using Zotero itself. It will take the process of collecting and organizing sources and incorporating footnotes or in-text citations to the next level.
