If you're looking for somewhere else to archive them, World of Spectrum might be interested. They have ZX80 and ZX81 books and software as well as Spectrum - and I don't see these listed.
Huh. I didn't know about that. Thanks for the info.
I don't know anything about the current maintainer or any of these disputes but I hope WOS keeps going; it's been going for over 20 years and amassed a lot of good stuff in that time.
Looks that the original maintainer get out, and the actual maintainer is in middle of the Vega plus torment.
At least archive.org would keep a copy of WoS
