Why Are Citations Important?


What Does a Citation Look Like?

A citation is typically found in two places:


In-Text Citations


In-Text Citations

Authors use in-text citations after they have paraphrased, summarized, quoted or otherwise used another author’s work.

Examples of in-text citations include parentheses, footnotes or endnotes.

Reference Lists

A reference list includes information on all of the sources an author used. It can also be called a bibliography or works cited.

Each item in the list includes information such as title, author and publication date.

A reference list is usually listed at the end of a paper with the exception of footnotes which are at the bottom of each page.

Why is this important?

The journal title is often what is listed in library catalogs.

How do you know if it is an article?

The presence of two titles (article and journal) are the biggest clue that this is an article. Volume Number and Issue Number are also big clues as books will not have those pieces in a citation.
