Get all links to any of the legacy-DSpace-REST installations in
.dspace_legacy_hosts() (PsychArchives plus the others verified
2026-09-11 – see the note at the top of this file): real hyperlinks from
the paper's own url table, plus a body-text fallback. The fallback
recognises a bare mention (no hostname attached) only for PsychArchives'
own handle prefix (20.500.12034) – see .dspace_legacy_parse() for
why the other installations' bare mentions cannot be resolved the same way.
This is the general (all-hosts) counterpart to psycharchives_links(),
which stays PsychArchives-only for anyone calling it directly.
