This protection is subject to an important limitation. The mere fact that a work is
copyrighted does not mean that every element of the work may be protected.
Originality remains the sine qua non of copyright; accordingly, copyright protection
may extend only to those components of a work that are original to the author. Thus,
if the compilation author clothes facts with an original collocation of words, he or she
may be able to claim a copyright in this written expression. Others may copy the
underlying facts from the publication, but not the precise words used to present them
.... Where the compilation author adds no written expression but rather lets the
facts speak for themselves, the expressive element is more elusive. The only
conceivable expression is the manner in which the compiler has selected and arranged
the facts. Thus, if the selection and arrangement are original, these elements of the
work are eligible for copyright protection. No matter how original the format,
however, the facts themselves do not become original through association.
