I can't remember where I saw this, but at some point, I saw or heard DA suggest three different Read/Review categories:
Actionable Read/Review: things you need to read and that you know you will have to take some further action on, like edit, forward, react to, etc.
FYI Read/Review: things you need to read or want to read, but won't be acting on. You might read them, and then toss them, or read them, and then file them in reference.
Junk/Browsing Read/Review: Catalogs, low-interest magazines and newsletters, and other things that you'll probably just want to skim and toss.
dabnyc, it sounds like the stuff you're asking about is in the FYI category. I have a folder for it that I keep handy. I try to touch the folder every couple of days to make sure stuff doesn't get too backed up in it.
