  One in five arXiv articles published in 2021 contained a URI to a Git Hosting
Platform (GHP), which demonstrates the growing prevalence of GHP URIs in
scholarly publications. However, GHP URIs are vulnerable to the same reference
rot that plagues the Web at large. The disappearance of software hosting
platforms, like Gitorious and Google Code, and the source code they contain
threatens research reproducibility. Archiving the source code and development
history available in GHPs enables the long-term reproducibility of research.
Software Heritage and Web archives contain archives of GHP URI resources.
However, are the GHP URIs referenced by scholarly publications contained within
the Software Heritage and Web archive collections? We analyzed a dataset of GHP
URIs extracted from scholarly publications to determine (1) is the URI still
publicly available on the live Web?, (2) has the URI been archived by Software
Heritage?, and (3) has the URI been archived by Web archives? Of all GHP URIs,
we found that 93.98% were still publicly available on the live Web, 68.39% had
been archived by Software Heritage, and 81.43% had been archived by Web
archives.
