Definition
An abridgment is a condensed summary or compendium of a larger work, retaining the principal ideas of the original in shortened form. In legal usage, the term carries two distinct meanings:
1. LEGAL COMPILATION. Historically, abridgments were the primary reference tools of English common law — alphabetically arranged digests of case law, statutes, and legal principles drawn from prior authorities. The great English abridgments of Fitzherbert (c. 1516), Brooke (1568), and Rolle (1668), followed by the more systematic works of Viner, Comyns, and Bacon in the eighteenth century, served the function now performed by modern digests. The term "digest" has largely supplanted "abridgment" in contemporary practice.
2. COPYRIGHT. An abridgment of a copyrighted work is a condensation that reproduces the substance of the original in shorter form. Whether a given abridgment infringes copyright turns on whether it is genuine — that is, whether it exercises sufficient independent intellectual labor in compression — or merely colorable, serving as a substitute for the original without adding meaningful transformation. A fair and genuine abridgment has historically been treated as a distinct work not constituting infringement; a colorable abridgment has not.

Common Language
Modern common usage (Wiktionary): The act of reducing or condensing something; an epitome or shortened form of a book or other work; also, the state of being lessened or deprived.
Historical common usage (Webster's 1913): The act of abridging or the state of being abridged; diminution or reduction; an epitome or compend of a book; that which cuts short or makes time pass quickly.
The common meaning tracks closely to the legal meaning in its general sense. The gap emerges in two specific legal contexts: first, in copyright law, where "abridgment" is a term of art with a specific analytical framework concerning infringement that common usage does not capture; and second, in legal history, where "abridgment" refers to a formal genre of legal compilation with its own lineage and authority — a meaning invisible to general usage.

Common Confusion
Abridgment is frequently conflated with digest in modern usage, and the two terms were historically used interchangeably by some writers. They are not identical. An abridgment in the classical sense compressed actual text and arguments from cases and treatises, often preserving something of the original voice. A digest is a more systematic classification of legal principles under topical headings, typically without extended quotation. Both Black's editions note explicitly that "digest" has now supplanted "abridgment" as the working term — meaning historical sources using "abridgment" should be understood to mean what a modern researcher would call a digest or case reporter.
Abridgment should also be distinguished from annotation, which supplements rather than condenses a source text, and from epitome, which is a near-synonym but carries no special copyright or historical-compilation meaning in legal usage.

Recognized Forms
/SUBTYPES
The classical abridgments recognized in legal historical literature fall into two periods:
Early English abridgments: Fitzherbert's Graunde Abridgement (c. 1516), Brooke's La Graunde Abridgement (1568), and Rolle's Abridgment (1668). These are primary historical sources, not secondary commentary, and carry significant authority in tracing common law development.
Later systematic abridgments: Viner's General Abridgment of Law and Equity (23 vols., 1742–1753), Comyns' Digest of the Laws of England (1762–1767), and Bacon's Abridgment (1736). These are more encyclopedic in character and bridge the genre of abridgment with the modern legal encyclopedia.

Why It Matters in Research
Researchers working in the Law Mind corpus encounter abridgment in three distinct research contexts, each requiring different orientation.
First, when reading historical sources — cases, treatises, or legal arguments from the seventeenth through nineteenth centuries — citations to "the abridgment" or to a named abridgment (Viner, Rolle, Comyns) are citations to what modern researchers would treat as a secondary source compiling earlier authority. These are not primary case reporters. Knowing which abridgment is cited and understanding its scope and methodology is necessary to evaluate whether the underlying authority is being accurately represented.
Second, in copyright research, abridgment appears as a specific doctrinal concept that predates modern fair use analysis. Early Anglo-American copyright cases drew a distinction between a genuine abridgment (permitted) and a colorable abridgment (infringing), a framework that fed into, but is not identical to, the contemporary fair use four-factor test. Researchers tracing the historical development of fair use or derivative works doctrine will find abridgment cases essential but must resist reading modern fair use analysis backward onto them.
Third, the terminological shift from abridgment to digest is a genuine historical trap. Nineteenth-century legal writers who describe consulting "the abridgments" are describing research tools that no longer exist under that name. The Law Mind corpus contains extensive material from this transitional period, and researchers should map references accordingly.

Historical Dictionary Support
The three source dictionaries are in close agreement on the core definition. All three editions of Black's and Rapalje & Lawrence define abridgment as an epitome or compendium of a larger work and identify the historical English abridgments by name. Both editions of Black's cite 1 Stephen's Commentaries as authority and include the observation — attributed to Sweet — that "digest" has supplanted "abridgment." This consistency signals a well-settled nineteenth-century understanding.
Rapalje & Lawrence adds the copyright dimension explicitly, noting that a fairly compiled abridgment does not violate copyright but a colorable one may. Neither edition of Black's develops the copyright analysis at length, reflecting that the primary research function of the term by the late nineteenth century was historical and bibliographic rather than doctrinal.
What the historical dictionaries do not address is the analytical framework courts had developed for distinguishing genuine from colorable abridgments. That doctrine lived in case law, not dictionary entries, and researchers should treat the dictionary definitions as entry points only.

Jurisdictional Note
The classical abridgments are English authorities and have no direct American equivalents under the same name. American legal publishing moved toward the digest form (West's American Digest System, regional reporters) without a transitional abridgment tradition. The copyright dimension of abridgment developed independently in both English and American courts, and the doctrinal frameworks diverged as fair use (U.S.) and fair dealing (U.K./Commonwealth) took separate paths.
