There is a video clearly explaining the case for Open Access to research journals. It is illustrated by Ph.D comics. I thank Tony Wright for bringing it to my attention.
A previous post The insatiable greed of commercial journals discussed some of relevant political background in the USA.
To curtail the influence the role of commercial journals, I think the least we can do is aim to mostly publish in journals run by professional societies such as American Physical Society and the American Chemical Society.
I also think research groups should be putting their "raw" research data sets online so others can analyse them independently.
I welcome comments.
