Yes. A compilation may contain multiple copyrighted word within it. Moreover, what appears to be one work may actually comprise multiple works. A copyright in an audiovisual work, for example, may exist for the productions and performances in it. A copyright in the screenplay may also exist. If the screenplay is an adaptation of a book, there may also be a copyright in the book. The musical score might include pre-recorded performances of musical works. Sound recordings involve at least two copyrights – one in the making of the recording and one in the musical or literary work that is performed in the recording. A multimedia unit of production, such as an album of musical recordings on vinyl or CD-ROM, might include distinct copyrights in production, performances, musical compositions, literary works, liner notes, cover art, compilation, and possibly other things. In addition, a copyright in a work, and in works within other works, may have multiple co-owners.
