Vital sources with Wayback Machine preservation links for independent verification.
This archive contains the vital sources cited in Before It Repeats — those where loss would undermine a key claim. Each URL was checked against the Wayback Machine's CDX index and, where no existing snapshot was found, submitted for preservation via the Save Page Now service. Archive generated March 17, 2026.
Paywalled academic sources (marked "Paywalled") are accessible through institutional library access but may not be archivable. PubMed articles are accessible at the original URL.
