Howdy,

I'm not quite sure what you are trying to achieve. If you want to end up with a single bibliography in the end why not just make one large bibliography in the root file and just have the cite commands in each included file.

In each included file put the line

% !TEX root = path/to/root/file

(e.g., if the included file is in a folder in the folder holding myrootfile.tex then path/to/root/file would be ../myrootfile.tex). This is so TeXShop ``knows'' what file to compile when you edit one of the included files.

Then try to use one of the latexmk engines. If you really want to be running latex (rather than pdflatex) move the latexmk.engine file from ~/Library/TeXShop/Engines/Inactive/Latexmk/ two folder up, to ~/Library/TeXShop/Engines/ and restart TeXShop (~/Library/ is the Library folder in your HOME folder). Finally put the line

% !TEX TS-program = latexmk

at the top of the root file. From then on just run Typeset->Typeset (Cmd-T) and all the necessary runs of latex, bibtex, etc., will automatically happen.

Also note that all the necessary bibliography packages (which ones are you using) are already part of TeX Live (installed by MacTeX) so don't need installing.

Good Luck,
