After the closure imposed by the COVID-19 emergency, the Library reopened to the public on Monday, May 18th 2020 by applying a rigorous access protocol, whose planning was conceived with absolute respect for the health of users and staff. Although the opening hours have not changed, except for the closure required for the room sanitization from 1:00 to 2:00 p.m., compliance with government safety provisions has required the reduction of study stations and the quota of entrances. Therefore an online booking system has been developed through moBi, the platform for managing and requesting volumes for consultation. In the reopening plan access and permanence were intended as aimed exclusively at consulting works and scientific documentation in paper format, and for this reason, already in the lockdown phase, the offer of electronic resources accessible also off campus was expanded through the OpenAthens service. Staff activities have been reorganized on the basis of the coexistence of smart working and face-to-face work. The emergency situation led to the strengthening of some activities, the weakening or suspension of others, as well as a certain creativity in the provision of services, in the idea of a gradual release and a progressive increase in the same, where circumstances allow for it.
