Types of references, types of detailed national standard references (that is, citation sources) are identified by a single letter: M— monograph C— collection of papers N— newspaper article J— journal article D— paper R— report, and the letter "z" is used for those documents that do not belong to the above types.

References are continuously coded with Arabic numerals in the order in which they appear in the text, and the serial numbers are placed in square brackets. If the file is referenced repeatedly, it is marked with the same serial number in the text. Generally speaking, the page number (or page number range) of a document cited once is listed in the following references.
