I've ordered all three issues of NGSLG, Casey.
Regarding copyrights..... To order a back issue of a mag is so easy, and inexpensive, it's really not worth going to the trouble to violate copyrights, and one's ethical self will feel better.
If a back issue is unavailable, and the publisher cannot supply page copies, then I'd say it's justifyable to make copies for non-commercial purposes --- and I'm sure no one but an absolute AH would prosecute you for doing so.
