For when “I think I have two” is not a system

Yes, the duplicate is a different creature.

One catalogue entry can describe the title. The copies beneath it describe the real objects you own: the pristine one, the battered one, the graded one, and the one currently hiding somewhere extremely safe.

The title is not the whole story

One clean record. Every real object underneath.

Keep one clean item record for the thing itself, then track every physical copy underneath it. No duplicate item names. No mystery suffixes. No “final-final-actually” spreadsheets.

A title-only list

Amazing Spider-Man #300

Qty: 3

One row says you own three. It cannot tell you which three, where they are, or what any single one is worth.

Give every copy its own facts

The first pressing and the scuffed spare are not the same job.

Condition, location, acquisition date, price paid, estimated value, and status all belong to the individual copy. Because a first pressing on display and a scuffed spare in a box are not doing the same job.

Switch copies, keep context

Choose a copy. The details follow the object.

Choose a copy and KolleK changes the details around it: where it lives, what it is worth, and what happened to it. The history follows the object, not the title.

History for this copy

Built for the things collectors actually collect

Better than a comma-separated note.

Variants. Editions. Duplicates. Graded items. The version you bought because the cover was different. They all deserve a record of their own.

KolleK might not be for you (yet) if…

You only need a list of titles.

One row per thing is plenty.

You do not care which exact copy you own.

The details can stay fuzzy.

Choose KolleK when…

You own duplicates, variants, editions, or graded objects.

Each physical copy gets its own record.

Condition, location, value, and acquisition details matter per object.

Because two copies are rarely interchangeable.

We will update this page when the product changes. The feature status page has the boring-but-important details.
