 :::::::*"Some people believe that the compilations of the work of other authors are not subject to copyright protection. This is not correct. In fact, the compilation of existing work may be considered an original expression subject to copyright. . . . A compilation is a copyrightable work that is the result of bringing together or arranging preexisting material (regardless of whether that material is protected by copyright) in an original way. Copyright protection is based on the original selection, coordination, or arrangement of the material, not the copyright status of the preexisting material itself."
