Zotero is a free, open source citation manager. It can help you to gather and organize sources for your research projects, and to create properly-formatted citations and reference lists.
Zotero connects to your web browser to help you quickly gather citation information as you search for sources, whether they come from the library catalog, article databases, or the open web. You can store PDFs of articles or snapshots of web pages, add notes or tags, and sort your sources into collections for different projects.
When you're ready to write, Zotero works with your word processor--MS Word, LibreOffice Writer, or Google Docs--to help you create citations and bibliographies in a wide variety of styles, from MLA, APA, and Chicago to thousands of journal-specific styles.
