The usebib package is a poor person's replacement for the
more powerful methods provided by biblatex to access data
from a .bib file. After

  \usepackage{usebib}
  \bibinput{biblio}

in the preamble, one is able to say

  \usebibdata{newton1687}{title}

for printing in the document the title of the work with
the BibTeX key `newton1687'. Access to other fields is
provided.

This is version 1.0 of the package
