The cited sources that are free to redistribute, mirrored here.
These 28 works from the bibliography of Precausal Substrate Theory are public domain or openly licensed, so a copy is kept here and the short link printed under each one resolves to that copy; it survives even if the original host disappears. The full bibliography is on the References page.
For the historical papers the copy is the original-language work, not a modern translation. Where the citation points at one part of a larger volume, only that part is kept, the single article from a bound journal volume, or the chapter a book is cited for. Each entry notes its licence, its source, and any such excerpting. Nothing behind a paywall is copied here; those references link to their source instead.
