    6.3.1 - Bibcodes

    The bibliographic codes are generated from the journal, volume and page information for each publication. The form of the bibliographic code is:
        yyyyjjjjjvvvvmppppa
    
    
    where:

    • yyyy: Year of publication

    • jjjjj: A standard abbreviation for the journal. A list of abbreviations is available.

    • vvvv: The volume number (for a journal) or an abbreviation that specifies what type of publication it is (e.g. conf for conference proceedings, meet for Meeting proceedings, book for a book, cong for congress proceedings).

    • m: Qualifier for publication:
            L: Letter
            P: Pink page
            Q-Z: Unduplicating character for identical codes
    
    • pppp: Page number.

    • a: The first letter of the last name of the first author.

    The fields are padded with periods (.) so that the code is always 19 characters long. The journal is left-justified within its 5 characters, and the volume and page are right-justified. New journal abbreviations should be unique, and follow existing naming conventions. Please consult the list of current journal abbreviations.

    This list should be checked for the abbreviations of journals as well as for conference proceedings or symposia. If you need to compose your own abbreviation for a conference, please try to use the first letter of each important word for JJJJJ, capitalizing the letter for a journal. For a conference proceeding or symposia, we use "conf" for conference abstracts or "proc" or for proceedings abstracts in place of VVVV. Bibliographic codes will be verified before they are entered into the system.

    PhD Theses should be named YYYYPhDT..........A where YYYY is the year and A is the author initial. When the abstract is merged into the system, a counter will be added, if necessary, in the PPPP field to determine uniqueness.

    Once a bibcode has been built, there is a Verification Utility available that allows the user to determine whether a given bibcode exists in the ADS.

    The bibliographic codes are selected so that they match the codes used by the SIMBAD project.
