Collection Catalog

Hobbyweight 1tracker · keeps what you put in

Whatever you collect — stamps, fountain pens, cast-iron pans, improbable teapots — there comes a day when you need to know what you actually have and what it is worth. The Collection Catalog is that reckoning made pleasant: each item, its category, condition from Mint to Poor, its value, and notes. Insurers, heirs, and your own curiosity will all be glad of it.

This is not a screenshot. It's the real tool, running right here — go on, put something in it.

What it keeps

Questions people ask

How do I catalog a collection for insurance purposes?
List each item with its condition and your best value estimate, and use the notes for provenance — where you got it, what you paid, any documentation. An itemised list is exactly what an insurer asks for after the worst has happened.
Can one catalog hold different kinds of collections?
Yes — the category field keeps the stamps away from the teapots while everything lives in a single list. One file, the whole hoard.
Who can see what my collection is worth?
Only you. The catalog runs offline in your browser with no account and no server; the values you record never leave the page. It is one HTML file you own — appropriately enough, part of the collection.
