Compile

To copy from various authors into one work. Implies the exercise of judgment in selecting and combining the extracts.* A compiler may take existing materials from sources common to all writers, and, by arranging them in combination in a new form, give them an application unknown before. Others may use the materials, but not his improvement. The "fair use" which is allowable applies to the materials, not to another's plan and arrangement. ' A compilation made from original sources is a new work. The fact of originality may be proved by another than the author. A compiler is an " author," within the meaning of the Constitution and the copyright laws.. A compilation, which is the result of labor devoted to gathering from original sources and to arranging in convenient form facts ■Mason's Appeal, 70 Pa. 29-30 (1871), cases; 77 id.
