A citation management tool (also known as a reference manager application or a bibliographic manager) can be a useful tool for anyone doing research. Reference managers allow you to:
Create bibliographies quickly and automatically format in-text citations with word processing software (Word, Google Docs, Open Office).
Collect citations as you research, and save them in a personal account.
Add citations automatically certain sources without having to cut and paste or retype the information.
Annotate citations and link them to full-text documents.
Organize citations into folders.
While a number of reference manager applications exist, the most popular ones among researchers are: Zotero, Endnote, Mendeley, and RefWorks.
Please use the tabs to decide which is best for you. One thing to keep in mind is that it can be hard to switch from one platform to another. You can export your citations, but transferring tags or folders will be difficult.
