How to catalogue your vinyl collection

Cataloguing sounds like a chore and is really just four things: scan what you can, identify what you cannot, capture the details that matter, and set aside the records worth insuring. Do them in that order and even a large collection goes quickly. This guide works whatever tool you use. Where it helps, we note how Cratemint handles a step.

Start with what you can scan

Barcodes reached records in the early 1980s. Anything pressed from roughly 1983 onward almost certainly carries one on the back of the sleeve, and that is your fast lane. A phone camera reads the barcode and matches it to a pressing in about a second, so a few hundred modern records is an afternoon of work, not a weekend.

Work a crate at a time rather than trying to clear the whole shelf in one go. Continuous scanning keeps up with the pace of flipping records, so you can settle into a rhythm: flip, scan, flip, scan. In Cratemint a scan lands the record on the shelf in under five seconds with a haptic on the match, which is the whole reason it feels like flipping a crate rather than doing data entry.

The records with no barcode

Records pressed before the early 1980s generally have no barcode, and neither do plenty of reissues that keep a vintage sleeve. These you catalogue by hand, which is slower but not hard. Search the artist and album, then choose the exact pressing using the clues printed on the record:

• The country and year of the pressing.
• The record label and, where it exists, the sub-label.
• The catalogue number, printed on the spine, the back of the sleeve, and the centre label.
• The matrix or runout numbers etched in the dead wax.

Those last two do most of the work, and they are worth understanding properly.

Pressing versus master, and why it matters

People use the word album to mean two different things, and cataloguing asks you to keep them apart. A master is the album in the abstract, the work itself across every edition ever made. A pressing, sometimes called a release, is one specific manufactured version of that album: a particular year, country, label, and catalogue number.

This is why matching a record is not simply naming the album. You are picking the exact pressing you own out of all the versions that share the same title, so the details on your shelf are true to the object in your hands.

Matrix and runout: the fingerprint in the dead wax

Tilt a record toward the light and look at the smooth band of vinyl between the last track and the centre label. That is the dead wax, or run-out groove, and etched or stamped into it you will usually find a string of letters and numbers. This is the matrix or runout, and it identifies the exact master and stamper the record was pressed from.

It matters because two pressings can look identical on the outside, same sleeve, same label, same catalogue number, and still be different pressings with different values. The dead wax is often the only place the difference shows. Collectors read these codes to separate a true first pressing from a later run, and you will sometimes spot the mark of a mastering engineer in there too. When you are unsure which pressing you have, the runout is where you look.

How long it really takes

Set expectations honestly and you will actually finish. Barcode records go at a few seconds each. Older records with no barcode take a minute or two apiece while you confirm the pressing. So a mostly modern collection of a few hundred is an afternoon, and a deep collection of older records is better done as a habit: a crate or two per sitting, a shelf at a time, rather than one heroic marathon that never gets started.

A good tool removes the friction rather than the records. Nothing should ever be lost because it would not match. In Cratemint, a record that cannot be matched becomes a ghost entry, a proper file card that sits on the shelf until you resolve it, so you keep moving instead of stalling on the one awkward pressing.

Keeping value records for insurance

If your collection has grown into something worth protecting, a small amount of record-keeping now saves a painful conversation later. Three things make a record insurable:

1. Condition. Grade each record on the standard scale collectors and dealers use: Mint, Near Mint, Very Good Plus, Very Good, Good, Fair, Poor. Grade the sleeve and the vinyl separately, because they often differ.
2. What you paid. Note the purchase price. It is the firmest number you have and the one an insurer trusts most.
3. A market estimate. Keep a sensible current value, treated as a guide rather than a guarantee, since prices for the same pressing move over time.

Then keep it exportable. The point of the record-keeping is being able to hand someone a clear document when it counts. Cratemint keeps your purchase price and a self-entered insurance value private to you, shows a caveated market estimate drawn from eBay asking prices, and exports an insurance summary you can pass to an insurer. It is private knowledge for your own peace of mind, not a portfolio ticker.

The short version

• Scan every record that has a barcode. That is most of the work.
• Identify the rest by artist, title, country, year, label, and catalogue number.
• Use the matrix or runout to confirm the exact pressing.
• Grade, price, and export the records worth insuring.
• Work a crate at a time and let nothing be lost.

Cratemint does all of this on iPhone: continuous scanning, a guided import of your Discogs CSV export, ghost entries so nothing is lost, and a private value layer for insurance. The free tier holds your whole collection.
