This looks ok: The Price of Digitization: New Cost Models for Cultural and Educational Institutions
I like this quote from the end of the summary for the above-linked symposium report:
"I ended by quoting Voltaire, "the best is the enemy of the good," and urging people to go for more material at lower costs and quality levels. I also think we urgently need help demonstrating why we need these projects. Institutions don't quantify the value of new information and fear that it is used by those outside their community; we may need a new definition of community." (http://www.ninch.org/forum/price.lesk.report.html)
Let's remember that: The best is the enemy of the good. Let's make it our mantra. I may have it tattooed on my butt. Or at least put it on my office door. (No one would see the tattoo.)
