The style manual published by the Council of Biology Editors, Scientific Style and Format: The CBE Manual for Authors, Editors, and Publishers, 6th. ed. 1994, is widely used not only in the life sciences and medicine but also in many engineering disciplines. In addition to extensive treatment of the conventions for scientific terminology, it present two systems of citation: a number-year system similar to APA style and a citation-sequence system, which uses numbers in the text that refer to a numbered list of references. Many other scientific and technical formats, such as the IEEE reference style, use variations of this general system.
