Teaching · For Teachers

Same cover. Different record.

One album can exist in a dozen pressings that share a cover and a catalog number but sound, and sell, very differently. The matrix number etched in the run-out groove is what tells them apart. Add each copy with its matrix and grades. The organizer groups copies of the same title, flags originals you cannot prove and the storage habits that warp and scuff vinyl.

What you finish with

Collectors grade the record and the sleeve separately. Most sales quote both, record first.

Reading the run-out

The matrix number is cut or stamped into the smooth band between the last song and the label. It usually repeats the catalog number with a side letter and a cut number, and may carry the initials of the engineer who cut the lacquer and a mark for the pressing plant. A higher cut number or a different plant mark means a different pressing.

For a music or history class

A shelf of records shows how music moved: 78s in shellac until the 1950s, then the 33⅓ LP and the 45 single in vinyl. Students can sort a collection by format and year and see when each one arrived.
