In the citation-sequence system, each source is given a superscript number the first time it appears in the paper. Any subsequent references to that source are marked with the same number. At the end of the paper, a list of references provides full publication information for each numbered source.
Entries in the reference list are numbered in the order in which they are mentioned in the paper.
