The short answer to this question from a report recently published by IFLA appears to be: not very well at all. The report documents a worldwide survey of 114 libraries, 83% of which said they had copyright-related challenges providing materials during pandemic-related facility closures. The report also provides direct quotes from a series of interviews of library professionals, discussing the challenges they faced and often how difficult digital access to necessary materials such as textbooks has been throughout the last two years. As one librarian from the United States explains:
“Times were tough. We were scrambling and worried about so many things – including the health and safety of our students, faculty and colleagues – and trying to spin up as much as possible in the way of service. There are certainly some vendors that we personally like the interactions with, but it felt to me like the publishers saw this as an opportunity just to make more money and not really an opportunity to build stronger connections with us and our library. They offered free things for a very limited period of time.“
The report is well worth reading in its 22-page entirety. You can find it here.
