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.
A good guide, if you're interested, is available here: https://guides.library.harvard.edu/zotero
