How many databases


I’m new to this reference database thingy but I wondered how many databases other users have? Do you have one for all subjects or does each subject you do have its own database… Are there good and bad points for either or?

Thanks in advance for any help.

IMHO the handling of a single database is easier. You can assign a keyword to each reference that says which subject it belongs to, so that you can filter your references by subject later.
