How can references be written

References can be written in several different formats depending on the citation style being used. Here are the general guidelines for writing references:

1. Start with the author's name: Write the last name followed by a comma and then the first initial of the author's first name. If there are multiple authors, separate their names with commas and use an ampersand (&) before the last author's name.

2. Include the publication year: Enclose the year of publication in parentheses after the author's name.

3. Add the title of the work: Italicize or underline the title of the work and use sentence case capitalization. For journal articles or book chapters, write the title in sentence case and only capitalize the first word and any proper nouns.

4. Provide the source information: Depending on the type of source, you may need to include additional information such as the journal name, book title, page numbers, volume number, edition, publisher, and location. Use the appropriate format for the source type (e.g., book, journal article, website).

5. End with the retrieval information (for online sources): If you are referencing an online source, include the URL or DOI (Digital Object Identifier) at the end of the reference.

Remember to consult the specific citation style guide (e.g., APA, MLA, Chicago) for detailed instructions on formatting the references.
