テンプレート:Selfref テンプレート:Infobox identifier The bibcode (also known as the refcode) is a compact identifier used by several astronomical data systems to uniquely specify literature references.
The Bibliographic Reference Code (refcode) was originally developed to be used in SIMBAD and the NASA/IPAC Extragalactic Database (NED), but it became a de facto standard and is now used more widely, for example, by the NASA Astrophysics Data System who coined and prefer the term "bibcode".
The code has a fixed length of 19 characters and has the form
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. Page numbers greater than 9999 are continued in the
M column. The 6-digit article ID numbers (in lieu of page numbers) used by the Physical Review publications since the late 1990s are treated as follows: The first two digits of the article ID, corresponding to the issue number, are converted to a lower-case letter (01 = a etc.) and inserted into column
M. The remaining four digits are used in the page field.
