Am trying to use reftex with emacs and am having trouble
getting the insertion of bibliographic citations to work
(everything else seems to work fine).

My LaTeX document involves several files spread out over a
main directory and various subdirectoreis.  Thus there is a
main.tex file in one directory and this uses \input to
include lots of chapters from subdirectories, e.g., main.tex
looks something like this:

   ...
   \chapter{Introduction}
   \label{ch:intro}
   \input{ch-01/chapter01}

   \chapter{Equilibrium Versus Nonequilibrium}
   \label{ch:equilibrium}
   \input{ch-02/chapter02}
   ...

I then use C-c = to jump to a chapter (say ch-01/chapter-01)
via the table of contents and this works fine. But then when
I try to insert a bibliographical citation chapter-01, I get
the error message:

      "No valid bibliography in this document, and no
      default available"

But if try to insert a citation in the main.tex file which
includes all the chapters, then the reftex mechanism works
fine. Reftex seems to be expecting bibtex info in the
subddirectory, doesn't seem to find it in the original main
directory.

Would anyone know why reftex can find my subdirectories and
open up the correct file but then can't find the bibtex
files associated with main.tex? How do I configure my shell
variables or reftex variables to make this work?

Note: I realize that I could move all the subdirectory files
up one level but I would strongly prefer to avoid that, not
a reasonable way to organize this large document.

	Thanks,
