Citation Managers Comparison from https://libguides.tru.ca/citationmanagement
Citation managers can help you organize and store all the citations you are using, which is very useful when you are working on a large research project. Since they can be integrated with many word-processing applications, citations managers can also help you create bibliographies and in-text citations as you work. Zotero is one of many different citation managers out there - it just happens to be free for anyone to use.
