Acquiring minds want to know: [readers' survey]

In preparation for a discussion at the Charleston Conference, I am asking librarians, vendors, publishers, and system vendors who read Against the Grain to answer a survey about how services and products that support information delivery and dissemination are developed and change over time. For example, document delivery (delivery for free or fee of articles or other publications to a library or to a requester) is a service being offered by more and more suppliers. With the apparently increasing need for this service the question, how the development of this service has affected other traditional roles or services among the four major players, may be asked. Moreover, the question arises whether there is increasing overlap in the services being offered directly to information seekers.
