This document discusses citations and provides guidance on how and why to cite sources. It notes that citations give credit, show how ideas are built upon previous work, help avoid plagiarism, and demonstrate research. Citations have two parts - in-text citations that identify sources within the body of work, and a reference list that provides full publication details. The document provides an example paper that demonstrates incorporating quotes and paraphrased information with in-text citations, as well as a corresponding reference list. It outlines the steps to build citations and cautions that citation software should be checked against style guides.
