Citation & Citation Style
|What is a citation?||What is a citation style and which one should I use?|
A citation is a way of identifying and giving credits to others' published works that you used to support your own research. Citations can also be used to locate sources of works, as well as avoid plagiarism.
A citation consists of two parts: in-text citation and reference list. In-text citations are brief references of sources within the text of the paper, while reference list is a complete list of references at the end of the paper.
A citation style defines the necessary information for a citation, how the information is ordered, and what format citations should follow.
SHTM students should use APA 6th style for their assignment. You can also check with your instructor in case there is any doubt.
