Final answer:
Footnotes and endnotes consist of two parts: the note reference mark in the text and the corresponding note text with additional information or citation. Footnotes are found at the bottom of the page, while endnotes are collected at the end of the document.
Step-by-step explanation:
The two parts of a footnote and endnote are the note reference mark and the corresponding note text. The note reference mark is a number or symbol placed in the text, which directs readers to the note, while the note text provides additional information or citation that would disrupt the flow of the writing if included in the main body of text. Footnotes appear at the bottom of the same page as the reference mark, while endnotes are collected together at the end of the chapter or document, before the works-cited list, and labeled as 'Endnotes' or 'Notes'.
It is essential in scholarly writing to use notes correctly to cite sources, offer explanations or additional information, and avoid plagiarism. When citing, all material borrowed from other sources must be adequately cited in the text and included in the works-cited list with full bibliographic details. Failure to properly cite sources can lead to accusations of plagiarism, which is a serious academic offence.
