Definition
AUTHENTICS (also Authenticae, Authenticæ). A term from the civil law tradition referring to two distinct compilations derived from the Novels of Justinian:
1. The primary and more significant collection: a complete Latin translation of Justinian's Novels (Novellae Constitutiones) made by an anonymous author, the identity of whom has never been established. Because the Novels were translated in their entirety, this collection was called the Authentics to distinguish it from abridged or epitomized versions. Burrill notes that the glossators referred to this collection as the Corpus Authentici, and it later came to be known as the versio vulgata — the common version.
2. A secondary collection of the same name: a compilation of extracts from the Novels assembled by the medieval jurist Irnerius (also rendered Irnier), who inserted them into the text of the Code at the points to which they related. This collection carried a reputation for inaccuracy and is the lesser-regarded of the two.
The Novels themselves were a component of the Corpus Juris Civilis — the great body of Roman law compiled under Justinian in the sixth century. The Authentics thus served as a practical bridge between Justinian's original Greek-language legislation and Latin-speaking medieval jurists who worked with the Code.

Common Language
Modern common usage (Wiktionary): A collection of the Novels or New Constitutions of Justinian, by an anonymous author.
Historical common usage (Webster's 1913): A collection of the Novels or New Constitutions of Justinian, by an anonymous author; so called on account of its authenticity.
The common-language definitions here track the legal meaning almost exactly — both Webster's and Wiktionary treat AUTHENTICS as a specialized historical term without an independent everyday sense. The only gap worth noting is that Webster's 1913 attributes the name to "authenticity" as a quality, while the legal dictionaries are more precise: the name derived specifically from the completeness of the translation (entire Novels, not an epitome), not from a general claim that the text was authoritative or genuine. That distinction matters when evaluating the term's place in civil law bibliography.

Common Confusion
AUTHENTICS should not be confused with AUTHENTICATION in evidence law. The two terms share a Latin root (authenticus, meaning genuine or authoritative) but have no doctrinal relationship. Authentication in modern American evidence law — governed by Federal Rules of Evidence 901 and 902 — concerns the procedural foundation for admitting documents and other items into evidence. AUTHENTICS is a historical bibliographic term describing medieval compilations of Roman law. Encountering one term in a source does not imply relevance to the other.

Why It Matters in Research
This term will appear in older civil law treatises, Roman law scholarship, and annotated editions of the Corpus Juris Civilis. Researchers working in historical civil law sources — particularly works citing Mackeldey, Merlin's Répertoire, or the glossators — may encounter AUTHENTICS as a bibliographic reference rather than a legal doctrine. Understanding that it refers to two separate compilations, not one, is essential to reading citations correctly: a reference to the Authentics in the context of Irnerius means something different in terms of reliability than a reference to the versio vulgata.
The two collections share a name but differ substantially in authority. The Irnerian extracts were considered inaccurate even by medieval standards, as Bouvier flags explicitly by citing Merlin. A researcher who treats all references to "the Authentics" as equivalent will misread the weight medieval and early modern jurists assigned to those passages.
This term has no operational role in modern common law research. It surfaces almost exclusively in: (1) historical introductions to Roman law and civil law; (2) scholarship on the transmission of Justinianic texts in the medieval period; (3) annotated editions of the Corpus Juris Civilis or Institutes; and (4) comparative law materials tracing civil law antecedents. The term does not appear in modern American statutory or case law.
The closest functional connection to modern legal research is the concept of authentication of documents — verifying that a source is what it purports to be — but that is a terminological coincidence, not a doctrinal lineage. Do not conflate.

Historical Dictionary Support
All four source dictionaries agree on the essential content: AUTHENTICS names a Latin translation of Justinian's Novels by an anonymous author, distinguished from Julian's epitome by its completeness, and a second Irnerian collection of extracts of disputed accuracy.
Burrill is the most bibliographically rich, identifying the collection's alternative Latin title (Corpus Authentici), its later designation as the versio vulgata, and its relationship to Julian's Epitome Novellarum. Burrill also cites Mackeldey directly (1 Mackeld. Civil Law 60, § 72), providing a traceable scholarly reference. Bouvier adds the Merlin citation, which is useful for researchers working in French civil law sources. Black's (both editions) and Bouvier track closely in substance.
None of the historical dictionaries clarify the precise historical moment the versio vulgata designation replaced the Authentics label, nor do they address whether the anonymous translation and the Irnerian extracts were ever confused in the manuscript tradition — questions a researcher encountering contested citations may need to resolve through Romanist scholarship outside the legal dictionary corpus.
Webster's 1913 is unusual here: it attributes the name to "authenticity" rather than completeness, which represents a slight but meaningful divergence from the civil law dictionaries on the origin of the designation.
