In-text citations appear within the body of your paper where you refer to the information you are citing. It is a brief way of telling your reader where you got your information, without interrupting the flow of your paper. If readers want to see full information for the source, they can jump down to the Reference section, where you'll list full citation information for each source.
Every reference at the end of your paper must have a corresponding in-text citation. Otherwise, your reader has no way of knowing how you used your sources.
In CSE the author’s name and the year of publication are listed in parentheses at the end of the sentence, which refers to the source. Page number(s) can also be added if you are referring to a particular part of a work.
