There's a fabulous long posting by David Rosenthal this week titled
"The Medium-Term Prospects for Long-Term Storage Systems" on the
evolution of various storage systems and technologies and associated
economics in the context of long-term preservation which I think will
be of interest to many in the CNI community.It synthesizes a good deal
of the work he's been doing in recent years, some of which he's
presented at CNI.
