REFER(1)                    General Commands Manual                   REFER(1)

       refer, lookbib - find and insert literature references in documents

       refer [ option ] ...

       lookbib [ file ] ...

       Lookbib accepts keywords from the standard input and searches a biblio‐
       graphic data base for references that contain those  keywords  anywhere
       in  title,  author, journal name, etc.  Matching references are printed
       on the standard output.  Blank lines are taken  as  delimiters  between

       Refer  is  a  preprocessor for nroff or troff(1) that finds and formats
       references.  The input files (standard input default) are copied to the
       standard  output,  except  for  lines between .[ and .]  command lines,
       which are assumed to contain keywords as for lookbib, and are  replaced
       by  information  from  the bibliographic data base.  The user may avoid
       the search, override fields from it, or add new fields.  The  reference
       data,  from  whatever  source,  are assigned to a set of troff strings.
       Macro packages such as ms(7) print the  finished  reference  text  from
       these strings.  A flag is placed in the text at the point of reference;
       by default the references are indicated by numbers.

       The following options are available:

       -ar   Reverse the first r author names (Jones, J. A. instead of  J.  A.
             Jones).  If r is omitted all author names are reversed.

       -b    Bare  mode: do not put any flags in text (neither numbers nor la‐

             Capitalize (with CAPS SMALL CAPS) the  fields  whose  key-letters
             are in string.

       -e    Instead  of  leaving the references where encountered, accumulate
             them until a sequence of the form
             is encountered, and then write out all  references  collected  so
             far.  Collapse references to the same source.

       -kx   Instead  of  numbering  references,  use labels as specified in a
             reference data line beginning %x; by default x is L.

       -lm,n Instead of numbering references, use labels made from the  senior
             author's last name and the year of publication.  Only the first m
             letters of the last name and the last n digits of  the  date  are
             used.   If  either m or ,n is omitted the entire name or date re‐
             spectively is used.

       -p    Take the next argument as a file of references  to  be  searched.
             The default file is searched last.

       -n    Do not search the default file.

             Sort  references  by  fields  whose  key-letters  are in the keys
             string; permute reference numbers in text  accordingly.   Implies
             -e.  The key-letters in keys may be followed by a number to indi‐
             cate how many such fields are used, with + taken as a very  large
             number.   The  default is AD which sorts on the senior author and
             then date; to sort, for example, on all authors  and  then  title
             use -sA+T.

       To  use  your  own  references, put them in the format described in pu‐
       bindex(1) They can be searched more rapidly by running  pubindex(1)  on
       them before using refer; failure to index results in a linear search.

       When  refer  is  used  with eqn, neqn or tbl, refer should be first, to
       minimize the volume of data passed through pipes.
