You don't have to do that manually. Some time ago members of the German TEX-D-
List put together a bash script, which takes all the PDFs recursivly and 
creates a *.tex file:

#+begin_src bash

#!/bin/bash
#
# pdfdir OUTPUT_FILE
#
# produces one big PDF file of all PDF files in .
#
if [ $# -ne 1 ] || [ -z "$1" ]; then
  echo "Syntax: pdfdir OUTPUT_FILE"
  exit 1
fi
FILE="$(echo "$1"|sed -e 's/\.\(pdf\|tex\)$//')"
for F in "$FILE" "$FILE.tex" "$FILE.pdf" "$FILE.aux" "$FILE.log" ; do
  if [ -e "$F" ]; then
    echo "$F already exists."
    exit 2
  fi
done
cat >"$FILE.tex" <<EOF

I found that very helpfull, but I did not use it recently.
