The SIMBAD and NED convention for Bibliographic Reference Coding (Bibcode)

The 19-digit reference code (such as 1994A&AS..103..135A) follows the coding system also used by the NED and SIMBAD databases.

A complete description of the reference coding has been published as a chapter of the book "Information & On-Line Data in Astronomy", 1995, D. Egret and M. A. Albrecht (Eds), Kluwer Acad. Publ. (also available as a Postcript file or as a PDF document).

You can obtain here the complete and up-to-date list of Journal reference codes.

The bibliography is updated on a daily basis, thanks to the efforts of the librarians of the Institut d'Astrophysique de Paris (IAP) and of the Observatories of Paris, Bordeaux and Strasbourg.
