Thanks for the feedback but I think she wants to go with Oliver, a number of schools in our area have switched to it from AccessIT and MLS and were a lot more impressed with the speed of the system (on AWS so no lag time at all) and functionality - She tells me the reports she can run with Oliver are miles ahead of the ones available with AccessIT and the interface appears to be more engaging - students can leave reviews, have book recommendations based on individual borrowing history etc.
