Zotero is an add-on for Firefox that will help you collect, manage, cite, and share your research sources. It lives right in your web browser and can be a useful tool for research purposes. You can collect information on books and other sources, archive entire web pages, and store anything from the web. You can organize your notes so that you can easily find what you are looking for within your research. The interface is very similar to iTunes. It even has a drag and drop bibliography and can cite in several styles. Zotero can be accessed anywhere, even from mobile devices. When finished, Zotero allows you to collaborate and share your collections with others.
Remember when doing research, teachers would require you to keep index cards for all your sources, well Zotero is meant to replace those index cards. If you are doing research or requiring students to do research this is a great tool. Students really struggle with citing sources and references and Zotero would be a great tool to help improve students abilities. I know that a lot of computers at school do not use Firefox, but it would still be worth sharing for home use.
