Thanks for clarifying. Free access to academic information for all is a worthy goal.

One would hope that organisations hosting digital libraries of academic journals would hold those in perpetuity. But often the subscriptions are exploitatively expensive, and I'm of the opinion that such information should be made available for free. In any case, having private libraries as a backup is certainly a good idea for a variety of reasons.

The same goes for preserving the volumes of data that will inevitably be quietly binned and forgotten to save server space.
