Zotero is a powerful, free and open source tool that is designed to make your life easier. It is used to collect, organize, annotate, and cite sources that you come across during your research. Zotero allows you to quickly save sources from various sites and databases into one account, and quickly generates bibliographies and in-text citations in the correct citation style. It works right in your browser, making it easy to save citations while you search. You can also take notes in Zotero, allowing you to store your reactions to a source right next to its citation.
