The Bibliotheca Teubneriana, or Bibliotheca Scriptorum Graecorum et Romanorum Teubneriana, also known as Teubner editions of Greek and Latin texts, comprise one of the most thorough modern collections published of ancient (and some medieval) Greco-Roman literature. The series consists of critical editions by leading scholars. They now always come with a full critical apparatus on each page, although during the nineteenth century there were editiones minores, published either without critical apparatuses or with abbreviated textual appendices, and editiones maiores, published with a full apparatus.
Teubneriana is an abbreviation used to denote mainly a single volume of the series (fully: editio Teubneriana), rarely the whole collection; correspondingly, Oxoniensis is used with reference to the Scriptorum Classicorum Bibliotheca Oxoniensis, mentioned above as Oxford Classical Texts.
The only comparable publishing ventures producing authoritative scholarly reference editions of numerous ancient authors, are the Oxford Classical Texts and the Collection Budé (whose volumes also include facing-page French translations with notes; the Loeb Classical Library, with facing-page English translations and notes, aims at a more general audience).
