The bibcode (also known as the refcode ) is a compact identifier used by several astronomical data systems to uniquely specify literature references.
Adoption [ edit ]
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 , which coined and prefers the term "bibcode". [1] [2]
Format [ edit ]
The code has a fixed length of 19 characters and has the form
-
YYYYJJJJJVVVVMPPPPA
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.
[1]
[2]
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.
