Definition
A person who produces an original work through the application of independent intellectual labor. In law, the term carries two related but distinct senses:
1. Copyright sense: The creator of an original work of authorship — literary, artistic, musical, or otherwise — whose creative effort gives rise to a protectable interest. The key requirement is that the work result from the author's own intellectual labor rather than mere mechanical reproduction or copying. Under modern copyright law, the author is the initial owner of copyright in the work, subject to exceptions such as works made for hire, where the employing party is deemed the statutory author.
2. Historical sense: The person whose mind composed the words, sentences, and ideas of a written work — particularly emphasized in early press and newspaper law, where identifying the author was essential to assigning legal responsibility for defamatory or seditious content.
Common Language
Modern common usage (Wiktionary): The originator or creator of a work, especially a literary composition; someone who writes books for a living; also used more broadly for any creator or cause of something.
Historical common usage (Webster's 1913): The beginner, former, or first mover of anything; hence the efficient cause; a creator or originator. One who composes or writes a book, distinguished from an editor, translator, or compiler.
Editorial note: In common usage, "author" is often narrowed colloquially to mean a professional writer of books. The legal definition is broader in one direction and stricter in another: broader because it encompasses creators of any copyrightable work (photographs, software, maps), and stricter because it requires that the work result from genuine independent intellectual labor — a mechanical copyist is not an author in law regardless of how much work they performed.
Common Confusion
AUTHOR vs. INVENTOR: Both are creators recognized by intellectual property law, but the terms operate under entirely separate regimes. An author's creation is protected by copyright from the moment of fixation; an inventor's creation requires patent prosecution and examination. The two are mutually exclusive as legal categories — a novel is authored, a machine is invented — though software and other technical works can complicate the line.
AUTHOR vs. COPYRIGHT OWNER: The author and the copyright owner are not always the same person. An author may assign copyright. Under the work-made-for-hire doctrine, an employer or commissioning party becomes the statutory "author" even though they created nothing. Researchers working in historical sources should note that this distinction was largely absent before modern copyright statutes codified it.
Why It Matters in Research
The legal meaning of "author" is deceptively unstable across time. In the eighteenth and early nineteenth centuries, English and American law used "author" primarily to assign liability — particularly in libel and seditious publication cases — rather than to confer rights. The rights-conferring sense grew with copyright statutes, but the definition of who qualifies as an author has been actively litigated well into the modern period.
Researchers should be alert to three specific traps:
First, early copyright cases often use "author" to mean the person responsible for the literary arrangement, not necessarily the underlying ideas. This matters when tracing disputes about compilations, indexes, and directories, where courts struggled to locate the creative contribution that qualified as "authorship."
Second, the photograph cases of the nineteenth century — particularly the U.S. Supreme Court's decision in Burrow-Giles Lithographic Co. v. Sarony, cited in the Black's 2nd Ed. entry — significantly expanded the legal concept by holding that a photographer could be an author. Researchers finding "author" in pre-1884 sources should not assume photographs or other mechanical reproductions were included.
Third, the work-made-for-hire doctrine, which deems an employer the statutory "author," is an entirely modern construct not present in Bouvier or either edition of Black's. Any historical source that discusses corporate or employer authorship should be read with that gap in mind.
The Bouvier entry, focused on newspaper authorship, reflects the libel and press-freedom context dominant in that period. The Black's entries, both tracking the Atwill v. Ferrett formulation, reflect a copyright doctrine still anchored in literary arrangement. Neither captures the current statutory framework under the 1976 Copyright Act.
Historical Dictionary Support
The Black's (1st and 2nd ed.) entries are essentially identical, both drawing from the federal circuit decision in Atwill v. Ferrett and reinforcing the intellectual labor standard: an author produces through their own effort "an arrangement or compilation new in itself." This formulation is notable because it foregrounds arrangement and compilation — suggesting that even derivative or assembled works can attract authorship, provided the organization is original.
Bouvier takes a different angle, defining authorship in the newspaper context through mental composition: the author is "the person whose mind composed the words, sentences and ideas." This definition is narrower in application (press liability) but broader in that it reaches the ideational content, not just its arrangement.
Neither dictionary anticipates the work-made-for-hire problem or the question of computer-generated or AI-assisted works, which have become the most contested authorship questions of the current era. The Anderson entry included in the source material is plainly misfiled — it describes the duties of an auditor, not the definition of "author," and should be disregarded for this term.
Points of genuine agreement: all sources require that authorship involve a human mental act. Points of divergence: Black's emphasizes novelty of arrangement; Bouvier emphasizes origin of ideas. Modern law has largely settled on originality of expression as the operative standard, leaving both historical formulations as partial predecessors.
