That’s exactly what I do. Every time I see great articles posted, I copy them and add them my collection of “required reading” for my kids. (now age 8 and 5, but I’ll make sure they read them in a few years!)
I try to at least book mark them. It drives me crazy to read something and then days or weeks later find I would like to refer to that article again! Goodness knows how many hours I’ve spent looking, frequently in vain, for some article I know full well I’ve seen recently.
