Conversion from other bibliography formats

Appendix E)  

Tools are available to convert UNIX troff/nroff bib/refer data
bases to BibTeX form, so if you only have the latter, then we can
undertake the conversion to BibTeX form at our end.

James Alexander's TIB format is similar enough to bib/refer that we
can automate conversion of TIB files as well.

We are willing to consider other formats as candidates for automated
conversion if
(a) the other format consists of PARSEABLE fields,
(c) the conversion software will be usable for other bibliographies,
(d) the bibliography is large, and
(e) updates subsequently are contributed in BibTeX form.

are the input to LaTeX for a bibliography, possibly prepared by
BibTeX.  This form is NOT useful for a bibliographic database,
because the fields are not readily identifiable and parseable by a
computer program.  It is essential to have visible markup that
identifies fields like author, title, volume, journal, publisher,
year, etc.

The same problem exists in typical library catalog entries, such as
this one from the Library of Congress catalog
