The Chicago Manual of Style has been prepared with an eye toward how we find, create, and cite information that readers are as likely to access from their pockets as from a bookshelf. It offers updated guidelines on electronic workflows and publication formats, tools for PDF annotation and citation management, web accessibility standards, and effective use of metadata, abstracts, and keywords. It recognizes the needs of those who are self-publishing or following open access or Creative Commons publishing models. The citation chapters reflect the ever-expanding universe of electronic sources--including social media posts and comments, private messages, and app content--and also offer updated guidelines on such issues as DOIs, time stamps, and e-book locators.
Give credit where credit is due. By properly citing the sources you use in your research projects you are both identifying the resources that you used to complete your work and you are formally acknowledging the authors or creators of those resources.
Political Science use Chicago Style.
