What happens when journals close after operating for a few years

More than a hundred or Hundreds of journals have disappeared from the internet. Journals provide a  record of scholarly work and are supposed to last for posterity. The by-line says that researchers have identified dozens of open-access or OA journals that went offline in the two decades spanning 2000-2020, and hundreds more could be at risk. Notably, the articles published by these OA journals have also vanished without any trace. These are not just articles published by "predatory journals" but even those published by journals associated with a "scholarly society or a research institution". Journals have sophisticated systems to back up and archive the scholarly record. The LOCKSS (Lots of Copies Keep Stuff Safe) Program launched by Stanford Libraries in 1999 is a pioneer in such efforts that have emerged over the years. 

Each of these options exists on the internet. For instance,

1. CLOCKSS
2. Portico
3. Public Knowledge Project’s Preservation Network (PKP PN)

A record of which journals have archived their content on which repositories is available at the Keepers Registry. Recently, we published an article about "Hundreds of independent midsize deletions mediate DNA loss in wild relatives of Red Jungle Fowl" in the journal Animal Gene (previously known as Agri gene). Soon after the article appeared online, the journal announced, "This journal will be closed after December 31, 2023. Authors are invited to submit their manuscripts to Gene Reports or Gene." While not associated with any society, the journal published by Elsevier can be considered an honest-to-god, non-predatory journal. Nonetheless, it will stop publishing articles at the end of this year. Our article may be the last or one of the last five articles to be published by this journal. One could even argue we killed this journal as our paper marked the end of this journal. 

With the ISSN of 2352-4065 and the title "Animal Gene." the journal is preserved on both the CLOCKSS Archive and Portico. Moreover, the pre-print of the manuscript was posted on bioRxiv before it was submitted to the journal. Given the availability of such multiple backups, it would appear our precious manuscript will survive the end of the world.
