content: Webpage Archival Services I’ve been using archive.[xx] for most of the citations in my book. The thing about archive.[xx] is that it has a half dozen or so TLDs available from which a page can be accessed, but those TLDs cycle in availability. If you visit an archived page from a TLD that isn’t available, the site automatically reroutes to a different TLD. I’m terrified that one or more of those TLDs is going to disappear completely, however, and instead of redirecting, the link will just be dead. I can’t have that. About half my links are already to archive.is, while the other half are archive.fo. Today I went to archive.fo and it redirected me to archive.md. Moreover, I can’t easily fix all the links in my book. I would have to redo several thousand links by hand to change TLD if the site goes offline in whole or in part. If whole, I would have to re-archive virtually every citation in my book on a different service. Some pages don’t save with archive.[xx], so I have to use web.archive.org, the Wayback Machine. Thing is, even Wikipedia admits that the Wayback Machine deletes its archives, and we know it does this for content it finds (((unacceptable))). Finally, the last few citations are direct links to scientific documents (often straight DOI links), but I’ve just read that there’s a lot of link rot among scientific and academic publications, which pushed me over the edge. I hear that perma.cc exists to archive academic sources, but again, what assurance is there that this service won’t delete (((objectionable))) content, or will last long enough for meaningful purposes? Thanks.
