Thanks for all the interest in this post, which I did not expect. This has over 150 boosts and a dozen replies which is absolutely bananas - I'm not sure I've ever posted anything that's had more than about 5 boosts before. I've had to mute this thread because I can't keep up with the notifications and I don't know what to say to all the individual replies, sorry.
It sounds like a lot of people think this collection of CDs is a lot more significant than it probably is, possibly because it's a post from someone you don't know that's getting boosted around the fediverse which makes it look important. It sounds like it might be possible to find someone who'd like it all.
A few points:
1. Hampshire, UK.
2. CDs have never had region coding, the way DVDs and BDs have.
3. I have little knowledge of music (classical or otherwise) so I couldn't say what type of classical music this is. I know a few of the CD cases are labelled with ranges of composer names (like "Bach - Griegg" or something - I have no idea what composers are there though, I'm just pulling names out of the air, and I haven't actually opened the boxes to look inside yet).
4. I have my doubts about whether any of this is particularly rare or would need to be "saved" and archived, but I suppose it's possible.
So, I guess I can tell my aunt there may be interest in someone acquiring the whole lot, so it might be worth a bit of time to try to catalogue at least some of it. Any ideas where I go from there?
