Similar situation here
I once had a pile of accumulated old RS and other free CDROMs that were filled with treasures like datasheets for long expired chips and other parts.
Alas RS saw fit to remove them over time to "save space" so decided to fight back by making my *own* datasheet DVD with literally every last one of them
spanning decades with an Acrobat reader and search engine built in.
Ended up making hundreds, but one day got a nasty email about it so stopped.
Might well update it and re-release with "Datasheet Archive 2.0, Ultimate Blackbeard Edition" out of sheer spite, on SD card or something.
Also containing an encrypted copy of all my research and unpublished scientific papers so when I choose, everyone has a copy at once.
