While many businesses have seen significant downturns during the pandemic, several scholarly publishers have reported increases in submissions in the first part of 2020.

Note that we count publications and the announcements and studies just mentioned are counting submissions. In what follows, I look at some data about publications in mathematics in 2020, with comparisons to 2019. the data come from four sources: Dimensions, Web of Science, the Mathematical Reviews Database, and the arXiv.
