Pondering OK scenarios for this thread, I can't come up with any. We have the following to go on.
1) You want to contact someone with a *digital* copy of this reference. That you specify digital copy suggests that you aren't interested in a specific piece of information being looked up but instead there is some feature of a digital copy that gives it value to you. Hmm, what might that be? I can't imagine what.
2) You don't want to openly share why you want this. These "I need this. I won't tell you why, but I want you to help me" type threads always work out so well for the original poster. Again, we don't get a "hey, can you look up something and tell me what it says". We get a "pm me, so we can have a secret exchange about your *digital* copy".
No one is going to give you a copy of this reference. Check your public library or pony up the price to buy a copy.
