In this edition of Thinking Out Loud , George and Joan (in the same location for once!) discuss the realities of circulation statistics. What if customers could define their own loan periods? Do shorter loan periods artificially inflate circ stats? How good a measure of library usage are circulation statistics? How much of a library's reliance on the use of circ stats is based on a lack of seeing how other things can be used as measures of success? Sure, circ stats are useful measures of how often something gets checked out, but how does a library measure the value of the transactions between the staff and the public? What other options might be used to measure how well-used a library is? As usual with George and Joan, there is lots of food for thought.
