Citations should be organized into folders for easy sharing and management. By organizing citations to folders users can create efficient workflows for collaborative research. Create an organic system of organization. Folders can be organized according to subject, author, class (citations for different classes), chronologically (for longitudinal studies over a singular topic), or a grouping that makes sense to the user for easy access.
The Texas Medical Center Library has a research guide for how to add folders and subfolders and can be viewed here.
