This should go without saying. You catalog gear for multiple reasons. First, for insurance. Second, in case you die. It’s a morbid thought but it’s the reality of life. If I died, I’d have over $12,000 worth of gear, Magic cards, and records that my family wouldn’t even know where to start with. I just sent the links of my catalogs to my dad: reverb.com has a ”my collection” feature and Discogs has the same feature for CDs and records.
