Just to express some agreement ith Peter Brantley when he wrote in PB keynote at DLF Forum:

I do not think it is the place of libraries to build applications that directly permit the sciences' domain consumption of content, but I do believe that libraries should develop services that allow our content riches to be discovered, manipulated, and recombined. I think, in other words, that we need to go up the stack, beyond the content, a bit more than we have in the past.

Without such services, how can we effectively interact with library materials, of which more and more are coming in digital form?
