Is the preface before or after the table of contents?

Front. The preface mainly explains the basic content, editing (translation) meaning, the process of writing, academic value and the introduction of the author and translator. As a leading paragraph, the preface can generally introduce the theme, background and purpose of the article, and provide a general framework for readers, which should be ranked before the table of contents. Therefore, the preface is in front of the table of contents.
