liner notes

Liner notes are the written material included with a music recording, typically printed on the packaging of vinyl records, CDs, or cassettes.

They often contain song lyrics, credits for musicians and producers, acknowledgments, and sometimes essays or commentary about the album's creation.

I learned about the session players by reading the liner notes.

In the streaming era, liner notes have largely migrated to digital formats or disappeared entirely, though collectors still prize them as part of the physical album experience.
