I agree, at times it is over-rated. You can essentially learn how to do anything on the internet. I have an MA, it was really one of those situations where you have to pay to play. I prefer open-access journals but I do have subscriptions to a couple. Tell her if she wants some free articles, and at times books, to create a profile on academia.edu. A lot of scholars from differing disciplines are on and upload their articles due to the open-access movement.
I keep all of my books regardless of how mundane or old. You never know when you might need to cite one or refresh a subject.
