PDP-8 "Introduction to Programming"

Hello, I'm a student interested in retrocomputing. That's why I started programming PDP-8 assembly a few days ago (Debian basically delivers all you need to do that, i.e. simh and palbart). One problem I have is the documentation. All that I found is either only a reference for the PDP-8 instructions or the documentation of PAL III assembler. The third thing I had as reference was the source code of OS/278. All in all, very incomplete. Now I learned about the "Introduction to Programming" by DEC, written for and about the PDP-8. Unfortunately I was unable to find a copy of it on the internet. Now I ask whether anybody of you has a copy of it (machine-readable preferred). In Austria, DEC hardware doesn't seem to have been very popular at that time, so documentation isn't easily available, either (it's even quite hard to get VAXen, fortunately I did).
