The '''bibcode''' is an identifier used by a number of [[astronomy|astronomical]] data systems to specify literature references. The bibcode was developed to be used in [[SIMBAD]] and the [[NASA/IPAC Extragalactic Database]] (NED), but is now used more widely, for example, in the NASA [[Astrophysics Data System]].<ref name=a>[http://cdsweb.u-strasbg.fr/simbad/refcode/refcode-paper.html NED and SIMBAD Conventions for Bibliographic Reference Coding], M. Schmitz, G. Helou, P. Dubois, C. LaGue, B. Madore, H. G. Corwin Jr., and S. Lesteven, published in ''Information & On-Line Data in Astronomy'', eds. Daniel Egret and Miguel A. Albrecht, Kluwer Academic Publishers, 1995. ISBN

where YYYY is the four-digit year of the reference and JJJJJ is a code indicating where the reference was published. In the case of a journal reference, VVVV is the volume number, M indicates the section of the journal where the reference was published (e.g., L for a letters section), PPPP gives the starting page number, and A is the first letter of the last name of the first author. Periods (.) are used to fill unused fields and to pad fields out to their fixed length if too short; padding is done on the right for the publication code and on the left for the volume number and page number.<ref name=a /><ref name=b /> Some examples of the code are as follows:
