Annotations mostly include the author's personal information, the source of research topics and cited documents, but the documents should be clear to the number of pages or even lines. He is different from the referee. References can be anything you read, as long as it is relevant to your paper, you don't have to quote it.

And "reference" is an indispensable part of academic papers, and people and experts with academic attainments have always attached great importance to "annotation" and "reference". When they read a paper, they usually read "notes" and "references" first. From the "notes" and "references", we can see the author's understanding of the relevant documents involved in the topic, especially the breadth and depth of his understanding of the frontier achievements of related issues. Therefore, when writing a thesis, we must attach great importance to "notes" and "references".
