Here's an interesting preprint (I am somewhat unclear where it stands in the publication process and if it's been through peer review, though it appears like it may come out in a UK Royal Society venue) which looks at publication patterns by discipline during the pandemic. There's been a lot of anecdote about what's happening here, but this is one of the few data-based presentations I've seen. My thanks to the amazing Gary Price for bring this to my attention.  See
