Zotero is a software that works with your web browser and word processor to collect, organize and cite your research.
*NOTE* If you turned in the same paper, or parts of the same paper, for another class and the professor used Turnitin or similar software, your new submission will be flagged. Turnitin will recognize the content. Be careful not to plagiarize yourself. If you wrote a paper for another class and would like to write on the same topic or use passages from an old paper talk to your professor first so they are aware that some of the content might be the same.
