bibtex setup .dir-locals.el

[edgar@openmail.cc]

Hello,

I would like to know how to set my ~References.bib~ as a dir-local 
variable for use with bibtex (org-ref, reftex). I have this in my 
~.dir-locals.el~. It keeps showing the global list of references. 
Thanks!

As an example:
#+BEGIN_EXAMPLE
   reftex-default-bibliography is a variable defined in ‘reftex-vars.el’.
   Its value is
   ("/Class/Biomat/Hw/Project/References.bib")
   Original value was nil
   Local in buffer report-biomat.org; global value is
   ("//Research/References.bib")

     This variable’s value is directory-local, set by the file
     ‘/Class/Biomat/Hw/Project/.dir-locals.el’.

   Documentation:
   List of BibTeX database files which should be used if none are 
specified.
   When ‘reftex-citation’ is called from a document which has neither a
   ‘\bibliography{..}’ statement nor a ‘thebibliography’ environment,
   RefTeX will scan these files instead.  Intended for using 
‘reftex-citation’
   in non-LaTeX files.  The files will be searched along the BIBINPUTS or 
TEXBIB
   path.

   You can customize this variable.
