The type of reference (i.e. citation) is identified by a single letter, as follows:

M monograph c paper n newspaper article

Journal paper D paper R report

For files that do not belong to the above types, use the letter "z" to identify them.

For English references, we should also pay attention to the following two points:

① The author's name adopts the principle of "surname comes first, surname comes last", and the specific format is: surname, initials. For example, Malcolm Richard Cowley should be Cowley, M.R. If there are two authors, the way of the first author remains the same. &; After that, the first letter of the second author's first name is put in front, and the last name is put behind. For example, FrankNorris and Irving Gordon should be: Norris, F.&; Gordon;

(2) Titles of books and newspapers are in italics, such as Mastering English Literature and English Weekly.
