refer

refer is a program for managing bibliographic references, and citing them in troff, nroff, and groff documents. It is implemented as a 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. , 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. , some reference management software (for instance, RefWorks) will import refer data.
