In CSE style, citations within an essay follow one of three formats.
The citation-sequence format calls for a superscript number or a number in parentheses after any mention of a source. The sources are numbered in the order they appear. Each number refers to the same source every time it is used. The first source mentioned in the paper is numbered 1, the second source is numbered 2, and so on.
The citation-name format also calls for a superscript number or a number in parentheses after any mention of a source. The numbers are added after the list of references is completed and alphabetized, so that the source numbered 1 is alphabetically first in the list of references, 2 is alphabetically second, and so on.
The name-year format calls for the last name of the author and the year of publication in parentheses after any mention of a source. If the last name appears in a signal phrase, the name-year format allows for giving only the year of publication in parentheses.
Before deciding which system to use, ask your instructor’s preference.
1. In-text citation using citation-sequence or citation-name format
VonBergen12 provides the most complete discussion of this phenomenon.
For the citation-sequence and citation-name formats, you would use the same superscript (12) for each subsequent citation of this work by VonBergen.
2. In-text citation using name-year format
VonBergen (2003) provides the most complete discussion of this phenomenon.
Hussar’s two earlier studies of juvenile obesity (1995, 1999) examined only children with diabetes.
The classic examples of such investigations (Morrow1968; Bridger et al.1971;Franklin and Wayson1972) still shape the assumptions of current studies.
