A practical guide to identifying pressings: detailed editorial view of labels and runout grooves
A locally held editorial image accompanying this feature on labels and runout grooves.

Identifying a pressing is a comparison exercise, not a single visual trick. Label copy, catalogue numbers, the runout groove and the sleeve can each narrow the possibilities, but the conclusion is strongest when several clues agree.

Start with the label

Record catalogue number, label layout and small-print wording before looking for a match. Photograph the whole label so a later comparison includes spacing and context, not only the most recognisable line.

Read the runout

The runout groove often carries marks that distinguish a cut or manufacturing stage. Treat every character as an observation first; handwriting, stamping and wear can make a confident reading difficult.

Compare the package

A sleeve can travel separately from a record. Use it as corroboration, not as proof. When label, groove and sleeve point in different directions, preserve the disagreement in the notes.

Source note. This feature uses observation-led editorial notes and clearly labels the limits of surviving material. It is written for readers who want a useful method they can repeat.
