Zotero is a research and reference management application that helps students, academics and writers collect, organise and cite information. It provides a central library for books, journal articles, conference papers, web pages and other research material.
The software is designed to support the research process, from discovering sources to preparing a finished document. Its desktop interface combines bibliographic records, attached documents and research notes, making it easier to maintain a consistent collection of references.
Zotero is particularly useful when working on substantial writing projects involving numerous sources. It integrates with word processors and offers tools for collaborating on research without requiring everyone to work on the same computer.
This is free and open source software.
