In our annotations what do we write? I don't understand how to do it. Thanks!

You need to have each source of information cited in TWO places:

1. the Works Cited page that is placed after the last page of your paper, and
2. in parentheses in the text of your paper, immediately after the quotation or paraphrase.

Use the column at the left as a table of contents.

Also for APA.
