What is a music publisher number?

A music publisher number, also known as a plate number or matrix number, is a number assigned by the publisher, used for sound recordings, printed music, other music-related materials, and video recordings. It is useful for identifying specific editions of a printed musical work or releases of a sound or video recording, and is sometimes used to estimate publication dates (see IMSLP's list of music publishers for more information).
