The citation styles of published references are mostly in different positions, orders and grammatical references. The number and types of citations reflect the simplicity, readability, date, author, publication and, of course, style of different priorities. There are also two most popular styles in major departments: documentary style and parenthesis style. Documentary notebook is the standard form of record source. It includes using footnotes or endnotes, so that your readers can get your channel information at any time, but it doesn't interfere with their reading your works. It involves how to choose journals when publishing papers. With so many different editing styles, how do you know which one is more suitable for your paper? First of all, we strongly recommend asking your teacher. Among them, several factors determine the appropriate citation style, including subject (for example, the priority of English class may be different from that of psychology class), academic expectation (the paper to be published may be different from the standard document in the middle of the year), term paper, the transfer of research purpose and your tutor's personal preference.
