The presentations and powerpoints from the LIANZA conference were published a little while ago. You can see videos and (PDFs of) presentations here. Two I liked were:
Carol Tenepir on ways of quantifying thevalue of academic libraries – critical incident analysis of faculty journal readings, return on investment of libraries in terms of grant income, etc.
Marilyn Fordyce and Paula Hasler on demand driven e-book selection: Moving beyond “just in time” collection development at the University of Otago.
