Using a reference management application can make tracking and citing secondary research much easier, especially when you're collaborating. Many of these tools will integrate with web browsers, word processors like Word, and synchronize your research across multiple devices. You can create groups, keep research for all your projects separate, and annotate PDFs within the application.
If you're going to be citing more than 10 sources, it is probably worth using a reference management application.
The VIU Library supports and offers tutorials for Zotero, a free and open-source reference management application.
