That is most probably an expensive big volume (and hence not free). You could perhaps find sources with free data to figure out the format from, like for example like FAA's Coded Instrument Flight Procedures (CIFP) though they only provide them in ARINC 424 versions 13, 15, and 18.

One of such sources might be this set of slides prepared by Lufthansa for a training program. They are most certainly incomplete, but should be a good starting point.
