What is a supplementary work?

For the purposes of determining whether a work is a “work made for hire,” the Copyright Act defines a supplementary work as something prepared to go with another work created by another author, to introduce or conclude that work, to illustrate, explain or revise that work, or to comment upon the work or assist others in using it. Obvious examples include forwards, afterwards, appendixes and indexes in a book.
