This is a bit tricky because it says they made changes to it, or at least that's what I take the comment in the email about editing to mean. I admit I don't know much about this, but there was trouble with this on Yahoo groups not that long ago that sparked a lot of discussion.
If it's a recipe or something like that, all you have to do is change one little thing, and the copyright no longer applies. Like say it's a cake recipe, and I change it to beat the batter for 3 minutes instead of 2, and use a 13x9 pan instead of a bunt pan, it's now my recipe and I can print it. At least that is how it was explained to me.
There is also the Freedom of Information Act, but for that to fly the source must be cited, and it must be shared for free.
