lookbib(1)              (BSD Compatibility Package)              lookbib(1)

NAME
     lookbib - find references in a bibliographic database

SYNOPSIS
     /usr/ucb/lookbib database

DESCRIPTION
     A bibliographic reference is a set of lines, constituting fields of
     bibliographic information. Each field starts on a line beginning with
     a "%", followed by a key-letter, then a blank, and finally the con-
     tents of the field, which may continue until the next line starting
     with "%" [see addbib(1)].

     lookbib uses an inverted index made by indxbib to find sets of biblio-
     graphic references. It reads keywords typed after the ">" prompt on
     the terminal, and retrieves records containing all these keywords. If
     nothing matches, nothing is returned except another ">" prompt.

     It is possible to search multiple databases, as long as they have a
     common index made by indxbib. In that case, only the first argument
     given to indxbib is specified to lookbib.

     If lookbib does not find the index files (the .i[abc] files), it looks
     for a reference file with the same name as the argument, without the
     suffixes. It creates a file with a .ig suffix, suitable for use with
     fgrep(1). lookbib then uses this fgrep file to find references. This
     method is simpler to use, but the .ig file is slower to use than the
     .i[abc] files, and does not allow the use of multiple reference files.

NOTE
     Probably all dates should be indexed, since many disciplines refer to
     literature written in the 1800s or earlier.

FILES
     *.ia      entry file

     *.ib      posting file

     *.ic      tag file
