Why Is Sharing So Much Harder Than Selling?

Barbara Fister has a provocative post on her Library Babel Fish blog at Inside Higher Ed -- see http://www.insidehighered.com/blogs/why-sharing-so-much-harder-selling -- that looks at how libraries have been bypassed as information providers.  We have all the stuff, but we have issues with being able to share it as broadly as Amazon and Google can, and we also have a huge marketing gap that keeps people from knowing what we actually have.  Her analysis of the expenses of accessing materials through libraries and through these providers is very interesting.
