So just how much vinyl do YOU own?

I live in a record store period,started collecting in the 60's. I stopped counting when I went over 15,000 and 3 weeks ago I was buying something at Bob's market in Santa Monica and while paying the cashier I looked over to the spot where I bought my first LP Introducing The Beatles on Vee Jay records. 
I have albums I haven't heard since buying them but my hope is to donate them to a Music College Dept. when I pass. My collection is diverse running the gambit from rnr,classical,blues and jazz. 

Cataloging? I go by genre, then alphabetically by last name in group or artist. For order  when released, if I dont know I google their discography.

I'm gifted vinyl all the time because people know I'm a collector and I take them and go through them.
A friend of mine whose mother passed gave me two boxes from which I found original pressings in mint shape  catalog of
Peter,Paul and Mary
Willie Nelson
Johnny Cash
Merle Haggard
Frank Sinatra 
I'm thankful because it filled in holes in my collection in genres I lacked.
I donate the the remainder to charities to sell.
