Hi C4L--
Just thought this might be a fun group to ping on this--sorry if it's off a
bit.

I'm looking for data sources that would help to portray aspects of the
differences between academic, national, and public libraries.  I think
academic rigor would be a big facet, but not sure how to represent that
quantifiably, other than audience level distinctions, and maybe cost
somehow.  Tentatively working with the idea for a model in 3D that has an
ontology spectrum (call # range?) as x-axis, some measure of quantity
(volumes held?) as y-axis, and academic rigor (per unit costs?) as the
z-axis.

If either the model or its data points tickle your fancy (or give it a
rash, for that matter), or if you've seen something done along these lines,
please let me know.

Much obliged,
--DBL
