Staff-less libraries are being piloted at the Toronto Public Library at Swansea and the Todmorden Room. This pilot is characterized as an expansion of service, as "extended hours." During these extended hours, the building will have zero staff. There will be "no impact on staffing levels" because they are simply not staffing these hours. If you need service, or run into trouble, you can access staff at another branch 'remotely.'
Staffless libraries were not a big hit in Ireland where it was understood that it's the first step to losing proper funding. Is this service?
