Using information fairly and acknowledging sources accurately is an essential part of any research project. Citations provide information to help readers locate the sources you use and provide a way for you to credit other scholars for their original ideas or findings. Most researchers use style guides or manuals to format their citations in a consistent way so their readers can quickly identify and locate cited sources.
An annotated bibliography includes a citation and a brief statement of its argument or purpose in your words. You can also include how you would use the source in your research.
Citation management tools are programs that collect records or citations from research databases (indexes, catalogs, etc.) that you can then organize for your research projects. They also help you cite your research by creating bibliographies, citations, and footnotes automatically.
