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 collection 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.
