My dad had a very large collection of books and records (and 8-tracks, for those who know what those are). My sisters and I donated most of the books to small town library, kept a few of the books and records that reminded us of him the most, and sold or gave away the rest. It was far too much stuff for any of us to ever read, listen to, or even store.
I intend to enjoy my collection at roughly the size it is for another 10-15 years (picking some up, selling some off), then whittle it down to the kubricks and a few other favorites. I'll talk to my daughters when I am selling parts off, to see if there is anything they remember particularly fondly and would want to keep. If I go before then, I've given my wife the tour of the spreadsheet so at least she will have a starting point to get rid of whatever they want to.
