I'm 68 and never plan to retire. Self-employed businessman. Wow, I posted 2 years ago and my collection has sprouted.
I currently have 31,100 LPs, 7,000 78s, 16,000 CDs. I've sold/disposed of 18,000 records (78s and LPs) over 4 decades. I have to cull 1000's of LPs and CDs.
I listen 2 hours per night.
Storage is a problem for me as well. In the past four years, I acquired by inheritance from late friends over 5,000 LPs, by purchase of Japanese pressed Jazz and 200+ 45 rpm LPs, another 1,100 LPS and from other deceased friends of friends, another 1,400 LPs. My storage room adjacent to my listening room is lined with floor to ceiling custom built record shelving (the center has steel drawer cabinets for CDs). It has 17,500 LPs/78s/CDs.
I installed a large Boltz CD rack in the rear corner of my listening room. It stores about 3,000 CDs, mostly in box sets.
I also doubled my CD collection with 3,750 from an unfortunately stroke victim who probably was the world expert on classical piano recorded performances and another 4,500 from a elderly gentleman who needed the cash for medical reasons and kept about 400 copies, CDs and 3,000 LPs.
I constructed a Tuff Shed with built-in record storage in a corner of my rear yard with 5,000 LPs and 78s. I also have about 5,000 LPs and CDs stored in two single garages.
The remaining 5,000 or so LPs and 3,800 CDs are located in my vacant parent's home 1 mile away.
Let's not forget books. I have two libraries in my home with a total of about 3,000 books and 1,000 periodicals.
Very classy and neat though. DVDs to 4k discs, about 700 located in pull-out shelving I designed and had constructed where a former 40" tube TV was located by the previous owner. Photos attached. (I did not install the brass ring on plate pulls yet)
The video tapes and in a closet. My own 150+ recordings are in my fire vault.
