Adoption of Bibcode
- The Bibliographic Reference Code (refcode) was originally developed for use in SIMBAD and the NASA/IPAC Extragalactic Database (NED).
- The code has become a de facto standard and is now used more widely, including by the NASA Astrophysics Data System.
- The term 'bibcode' was coined by the NASA Astrophysics Data System and is preferred.
- The code is used to uniquely identify bibliographic references in scientific literature.
- It consists of a fixed length of 19 characters.

Format of Bibcode
- The code follows the format: YYYYJJJJJVVVVMPPPPA.
- YYYY represents the four-digit year of the reference.
- JJJJJ is a code indicating where the reference was published.
- VVVV represents the volume number in the case of a journal reference.
- M indicates the section of the journal where the reference was published.
- PPPP gives the starting page number and A is the first letter of the last name of the first author.
