    2.4 - Searching by Reference Information

    2.4.1 - Searching by Journal/Volume/Page

    The Journal/Volume/Page query page allows you to find articles from journal references by year, journal, volume, and/or page. Any of the fields is optional. The query will return all references that match the input parameters.

    The journal name can be specified either as the full journal name (e.g. "Astrophysical Journal Supplements"), or by specifying the journal's bibliographic code abbreviation (e.g. "ApJS"). If the journal name as entered does not uniquely identify the publication, a menu listing close matches will be displayed.

    The entries in any of the input fields can contain the wildcard character "?" (one wildcard character). For instance 2??1 in the page field finds pages 2001, 2011, 2101, etc.

    2.4.2 - Searching by Reference

    The Reference query page allows you to find articles from journal references by author and year, and optionally journal, volume, and/or page. The query will return all references that match the input parameters. The input can have several formats:

      1: author [author ...] year [journal abbreviation [volume]]
        (eg Smith Jones 1999 ApJ)
      2: author [author ...] et al year [journal abbreviation [volume]]
        (eg Smith et al 2001 SPIE 4500)
      3: author [author ...] and author year [journal abbreviation [volume]]
        (eg Smith Miller and Jone 1998)
      4: full reference string from a journal citation
        (eg Smith et al 2000, A&A 362, pp. 333-341)
    
    
    Versions 1 and 2 search for articles with the listed authors, with the first author in the list as the first author of the article, and all listed authors as co-authors. There may be other co-authors in the article, except for version 1 with one author, which searches for articles with a single author.

    Version 3 searches for articles with the listed authors, with the first author in the list as the first author of the article, the last author in the list as the last author of the articles, all authors in the list as authors in the article, and the number of authors in the list as the number of authors in the article.

    Versions 1, 2, and 3 may not contain any punctuation. They search for articles in the specified year, and optionally restrict the search to a specified journal.

    Version 4 parses a complete reference string and returns the specified article if it can be found in the database.



    2.4.3 - Searching by Bibcode

    The bottom of the form allows retrieval of abstracts by bibcode. This field also may contain the wildcard characters "*" (zero or more wildcard characters, at the beginning or end of the bibcode) and "?" (one wildcard character, anywhere in the bibcode). Whole or partial bibcodes may be entered. For example:
      1984ApJ...276..233P  returns only that reference
      1984ApJ              returns all 1984 ApJ entries
      *ApJ...400           returns all entries from ApJ volume 400
      198?ApJ..????L       returns all ApJ letter articles from the 1980's
    
    
    Note: For page numbers greater than 9999, the page number is continued in the 14th column.

    Note: The ADS treats all bibliographic codes as case-insensitive!
