Zotero is a web browser plugin that saves citation information from web pages and formats bibliographies. Zotero is free, open source, and only available for the Firefox browser. The newest version of Zotero was released on June 17, 2008, and is fully compatible with Firefox 3.
Zotero combines elements from other software programs to create a powerful tool for managing and using information. Running inside your web browser window as you surf the web, Zotero automatically senses the type of material you are viewing (e.g., Library Catalog records, article PDFs, book PDFs, newspaper articles, films, web pages, etc.) and displays an icon relating to the type of material in the web browser address bar. Click the icon and the complete bibliographic citation information for this item is added to your Zotero collection. The screenshot below displays a Zotero collection of books, a newspaper article, and a journal article.
You can create multiple collections and include items in more than one collection simultaneously. Once you have added an item to a collection, you can tag it with keyword(s) that describe its meaning. Use the tag panel (show below) to view and search all tags in your collections.
In addition to storing information, Zotero lets you interact with your collected items. You can add notes to individual items, link notes between multiple items, or write notes about entire collections. If you capture a web page, you can add annotations to the page. This screenshot shows 2 notes and a screenshot attached to the citation for a journal article by Hillyer et al.
Use Zotero to create bibliographies with Microsoft Word, Open Office, or Google Docs. Multiple styles are supported, including American Medical Association (AMA), American Psychological Association (APA), National Library of Medicine, Nature journals, Cell journals, and Council of Biology Editors (CBE). New styles are added frequently.
