Each style includes methods for in-text citations that allow you to reference sources directly within the text, making it easier for readers to find the corresponding source details.

While each format labels it differently, all require a list of sources at the end of the document, ensuring that readers can access all referenced materials in a detailed and organized manner.

Formatting Guidelines:

Each citation style has specific guidelines regarding margins, font, spacing, and overall document structure. These guidelines help maintain a professional and consistent look throughout the document.

In-Text Citations:

Punctuation:

MLA uses minimal punctuation in its citations. APA uses commas and periods where appropriate, and flexible punctuation is allowed in footnotes. Chicago style has varying punctuation rules that can differ based on the type of source.
