Definition
A publisher is any person or entity that makes content publicly available — whether through manufacture, distribution, or circulation — and bears legal responsibility for that act of publication. In legal contexts, the term carries significance across several distinct bodies of law:
1. Defamation law: A publisher is any party who disseminates a defamatory statement to a third person. Liability attaches broadly — not only to the originating author but to anyone who reproduces or circulates the material, regardless of knowledge of its contents.
2. Copyright and intellectual property law: A publisher is the person or commercial entity that prepares, reproduces, and distributes an authored work to the public, typically under a contractual arrangement with the author. The publisher may hold or administer certain exclusive rights in the work.
3. Press and media law: A publisher is the proprietor or controlling entity behind a newspaper, magazine, periodical, or broadcast outlet — legally distinct from the editor and the printer, though all three may share liability depending on jurisdiction and context.
Common Language
Modern common usage (Wiktionary): A person or company that publishes, especially books; also used in software contexts for a system that sends notifications to subscribers.
Historical common usage (Webster's 1913): One who publishes; as, a publisher of a book or magazine.
Editorial note: Common usage centers on the book trade and commercial media. The legal definition is materially broader — a person who reads a defamatory letter aloud to a third party, or hands it to another, is a "publisher" in law regardless of any commercial dimension. Researchers treating "publisher" as synonymous with "book publisher" will miss the full sweep of defamation doctrine, where any party in the chain of communication can qualify.
Common Confusion
Publisher vs. Printer vs. Editor: These three roles are often conflated in historical sources and, to a lesser extent, in modern press litigation. The printer produces the physical object; the editor controls content selection and gatekeeping; the publisher is the party responsible for the act of dissemination itself. In defamation law, all three may be liable, but on different theories. Historically, printers faced criminal liability for seditious libel even when acting as mere mechanical producers; modern law has substantially narrowed printer liability while maintaining or expanding publisher liability, particularly for online platforms. Anderson's cross-references editor, manufacturer, printer, and the verb "utter" as related concepts — a signal to researchers that these roles overlap but are not interchangeable.
Recognized Forms
/SUBTYPES
Primary publisher: The originating entity that first releases material to the public. In defamation, bears full liability from first publication.
Republisher: A party who reproduces or redistributes previously published material. Treated as a new publisher for each act of republication under traditional common law — the "republication rule."
Distributor (limited publisher): A party, such as a bookseller or library, that distributes without editorial control. Historically treated as a publisher for strict liability purposes; modern law has softened this in many jurisdictions, requiring knowledge or reason to know of defamatory content.
Platform publisher: An emerging category in internet law. Online platforms hosting user-generated content have contested their status as publishers, with significant statutory implications (see Section 230 of the Communications Decency Act in U.S. law).
Why It Matters in Research
The defamation dimension is the most legally consequential and the most likely to catch researchers off guard. Historical sources consistently hold that a publisher is liable as if they were the author, with no knowledge defense available under classical common law. This strict liability rule — stated plainly in Bouvier and traceable through the treatise authorities cited there — is not the universal rule today. Researchers working with pre-20th century materials should not assume that historical publisher liability maps onto modern doctrine without careful attention to jurisdictional evolution.
For copyright researchers, the publisher-author relationship shifted dramatically with the advent of work-for-hire doctrine and modern statutory copyright regimes. Historical dictionary treatments focus on the act of dissemination; they do not capture the contractual and rights-assignment architecture that now defines the term in publishing industry practice.
The rise of digital platforms creates a genuine terminological fault line. Whether a social media company or search engine is a "publisher" — and therefore exposed to defamation liability — or a "distributor" or neutral conduit is one of the most actively litigated definitional questions in contemporary media law. Historical dictionary entries are silent on this entirely.
Anderson's entry is unusually rich in cross-references and signals that "publisher" is a relational term: its meaning shifts depending on whether the surrounding legal question involves libel, copyright, press regulation, or commercial distribution. Researchers should trace those cross-references rather than treating any single definition as complete.
Historical Dictionary Support
The four source dictionaries converge on a core definition: a publisher is one who makes a thing publicly known, whether by personal act or through an agent. Black's (both editions) emphasize the commercial book-trade sense — manufacture, promulgation, and sale. Bouvier adds the explicit defamation consequence: liability as author, knowledge irrelevant, regardless of justification.
Anderson's is the most analytically useful of the four. It observes that a writing as well as a printing may be "published" — a point of genuine legal significance that the commercial-centered Black's definitions obscure. Anderson also notes that what constitutes publication (i.e., the act of making public) can itself be a contested legal question, which is correct and important. This entry gestures at the publication/act distinction that modern defamation doctrine has developed into a substantial body of law.
Bouvier cites Coke (9 Co. 59), Odger on Libel and Slander, Hawkins' Pleas of the Crown, and a Massachusetts federal circuit report — all real authorities for the classical strict liability rule. These citations remain useful entry points into the common law foundation, though researchers must verify that they are reading pre-20th century doctrine rather than current law.
What the historical sources collectively miss: the author-publisher contractual relationship, copyright assignment, the distributor/publisher distinction in modern defamation, and any treatment of non-print media. The 2nd edition of Black's appends a truncated entry for "pudicity" immediately after publisher — a printing artifact that occasionally appears in digitized versions and should be disregarded.
Jurisdictional Note
Defamation liability for publishers varies significantly between the United States and Commonwealth jurisdictions, and among U.S. states. U.S. federal law (Section 230) grants broad immunity to online platforms from treatment as publishers of user-generated content — a protection unavailable under UK, Australian, and most other common law systems. Researchers should not generalize from any single jurisdiction's treatment of platform publisher status.
