US Copyright Office Compendium of US Copyright Office Practices… (1984)

Compilations defined. The copyright law defines a "compilation" as a work formed by the collection and assembling of preexisting materials or of data that are selected, coordinated, or arranged in such a way that the resulting work as a whole constitutes an original work of authorship. The law also states that the term "compilation" includes "collective works," which are works, such as a periodical issue, anthology, or encyclopedia, in which a number of contributions, constituting separate and independent works in themselves, are assembled into a collective whole.
