Word automatically generates a bibliography from the sources you used to write your paper. Each time you add a new citation to your document, Word adds that source so that it appears in the bibliography in the proper format, such as MLA, APA, and Chicago-style.
When you've completed these steps, the citation is added to the list of available citations. The next time you quote this reference, you don't have to type it all out again, just click Insert Citation and select the citation you want to use.
Important: APA and MLA can change their formats, so you’ll want to ensure that these format versions meet your requirements. You can create your own updated version of a style or build custom styles. For more information see Bibliography & Citations 102 – Building Custom styles.
If you want to create a bibliography from your sources, do the following:
Similar to the Table of Contents builder in Word, you can select a predesigned bibliography format that includes a title, or you can just click Insert Bibliography to add the citation without a title.

You can't automatically generate citations in Word Online. Word Online preserves the bibliography in your document, but it doesn’t provide a way to create one.
Instead, if you have the desktop version of Word, select Open in Word to open the document.
When you’re done and you save the document in Word, you’ll see the table of contents when you reopen the doc in Word Online.
