Getting rid of "stuff"

The Scandinavians refer to it as “ death-cleaning’ which I find a bit alarming. Instead I prefer to think of it as de-cluttering and I am about to start the process.
 
But what about books? I can envisage getting rid of a lot of my possessions,  Covid has made us all re-assess our possessions as we realise that we neither use nor need a fraction of what we own.
 
Books though are special. They hold a special place in our affections and they are the last to be subjected to  “death cleaning”.

Dont know where to start?
