The 'tag' field associated with each paper can be used to further separate papers, for example by species, or the type of data ('trait', 'yield', 'photosynthesis') that they contain. When naming a group, folders so that instructions for a technician would include the folder and the tag to look for, e.g. "please enter data from projectx" or "please enter data from papers tagged y from project x".

If you are managing a Mendeley folder that undergraduates are actively entering data from, please plan to spend between 15 min and 1 hour per week maintaining it - enough to keep up with the work that the undergraduates are doing.
