I am using lyx and have to insert citation by following rules. I could not find any specific citation style in lyx.
References should be presented in the following style:
Journal Paper: Fujar, B.R., Smith, R.N., Jackson, T.R., et al. 1996. Navigating gopherspace with neural implants. J. Neurol. 10, 275–280.
Book: Hillis, D.M., and Moritz, C. 1991. Molecular Systematics. Sinaur Associates, Sunderland, MA.
Chapter within Edited Book: Knight, J.R., and Myers, E.W. 1992. Approximate regular expression pattern matching with concave gap penalties, 66-76. In Chrochemore, M., and Galil, Z., eds. Combinatorial Pattern Matching. Springer-Verlag, New York.
Citation of references in the text: References in the text should be cited by author names and publication year. When a text citation includes one or two authors, list all authors and the publication year, e.g., Smith (2008) or Smith and Jones (2008), but for text citations for three or more authors, cite the first author only followed by et al. and the publication year, e.g., Smith et al. (2008).
