Refer (software)

refer
Original author(s) Mike Lesk
Operating system Unix-like
Type Reference management
License depends on implementation

refer is a program for managing bibliographic references, and citing them in troff documents. It is implemented as a troff preprocessor.

refer was written by Mike Lesk at Bell Laboratories in or before 1978, and is now available as part of most Unix-like operating systems. A free reimplementation exists as part of the groff package.

As of 2015, refer sees little use, primarily because troff itself is not used much for longer technical writing that might need software support for reference and citation management. As of 2016, some reference management software (for instance, RefWorks) will import refer data.

refer works with a "reference file", a text file where the author lists works to which she might want to refer. One such reference, to an article in a journal in this case, might look like:

The author then can refer to it in her troff document by listing keywords which uniquely match this reference:

A refer bibliographic database is a text file consisting of a series of records, separated by one or more blank lines. Within each record, each field starts with a %-sign at the beginning of the line and one character immediately after. The name of the field should be followed by exactly one space. And then by the contents of the field. Empty fields are ignored. The conventional meaning of each field is shown in the table below. Compare this scheme with the newer EndNote scheme which uses a similar syntax.
