Here at UC San Diego the situation is similar to many other universities as we rapidly flip our classrooms from in person to online due to the #COVID19 situation. The library remains open and librarians mobilize to support our faculty, students, staff, and even the larger public with information on the virus (COVID 19 resources: official word by our health sciences librarian), government resources (Coronavirus by our gov docs librarian), and even legal access to resources as courses are moved online to #flattenthecurve.
This is an opportunity for the campus staff, especially EdTech and Centers for Teaching and Learning as they offer strategies for remote instruction, to partner with libraries. Mention of the application of Fair Use (COVID-19, Copyright, & Library Superpowers) or utilizing Open Educational Resources #OER when posting resources online, even on password protected learning management systems (we use CANVAS) is imperative. Librarians are sharing this information and resources through list-serves (SPARC OER) and guides (also, just straight up talk to your librarian for resources).
