Zotero is the research assistant program I chose to use after spending time and money looking at multiple pieces of software. Zotero — hands down — has the best features of any. You can organize research, find new research, collaborate with peers, create a bibliography, and apply multiple tags (categories) to articles. Tagging was the clincher for me, as it makes it easy to locate information on “social justice” or “inclusive” or both.
