It does have a few limitations, such as an inability to search for key words WITHIN the body of my notes (i.e. when I search for a term it pulls up the entire text, but won’t refine more closely than that); and sometimes I want to classify items for which they have no category (e.g. an entire folio full of documents at the archive, not just a single letter). Then zotero ties one to using firefox, which some people may not like since it tends to use up a lot of disk space, and can make other programs run more slowly. But it is constantly under renovation, so also now allows for including artwork among its “item types,” and that’s a huge improvement…
