"Eighty-four online-only, open-access (OA) journals in the sciences,
and nearly 100 more in the social sciences and humanities, have
disappeared from the internet over the past 2 decades as publishers
stopped maintaining them, potentially depriving scholars of useful
research findings, a study has found.

"An additional 900 journals published only online also may be at risk
of vanishing because they are inactive, says a preprint posted on 3
September on the arXiv server. The number of OA journals tripled from
2009 to 2019, and on average the vanished titles operated for nearly
10 years before going dark, which “might imply that a large number …
is yet to vanish,” the authors write."
