What to do with a large collection

I gave away hundreds of Cds years ago..... now I'm buying them back.... who knew?

I too have some CDs I’d like to get rid of but I listen to CDs about as much as I listen to vinyl. I tried the streaming route but did not like it and sold my streamer and DAC. Of the 3 formats, streaming was the worst sounding with vinyl the best and CDs a close second. I continue to buy CDs because they are less expensive than vinyl and there is more choices than vinyl. Plus there are some amazing CD players available these days.

Our local friends of the library group does book sales where they also sell CDs. There are often many classical CDs. You won't get any return on your investment but it will do a great deal of good for the local library. 

I wonder how many of those cds have "cd rot"? I have a collection of around 500 cds that go back to the 80s. I'm finding that a few from the 80s and 90s have "self destructed". I have always stored them properly,  but it's my understanding that some of the materials contained in the cds, especially the older ones,  cause the layer containing the digital info to corrode.  It appears to the eye as a "cloudiness " on the surface. I'm curious as to how many other collectors are experiencing this.

I’ll take the CD’s. Just recently got a new disc player and really enjoy classical music
