Our tour guide explained that Printed Books is the most frequented library section. In addition to regular users, Printed Books receives 10-15 emailed research queries/day. Library staff is able to offer patrons 20 minutes of free research assistance; after that, patrons are charged $100/hour.
Guildhall library uses the fairly ubiquitous Talis software for their OPACs. It takes 10-15 minutes for a requested book to be retrieved from the library's closed stacks. Internet access is free.
