How something is cited will depend on whether it is in your bibliography, a list of references at the end of the paper, or within the paper itself. Also citing differs depending on what format you are using, print or electronic.
Citing Sources for a Bibliography
Citing Sources Within Your Paper
Citing Online/Electronic Sources
Create citations in MLA, APA, Chicago, CBE/CSE formats for books, journal articles, book chapters, etc.
Citation management tools like Zotero enable you to capture citation information about each book and article you are citing in order to help you create bibliographies, add footnotes, endnotes, etc. They even work in concert with word processing software to allow you to create the bibliography, add footnotes or endnotes while you are writing your paper!
