Orthodox Tewahedo biblical canon

The Orthodox Tewahedo biblical canon is a version of the Christian Bible used in the two Oriental Orthodox churches of the Ethiopian and Eritrean traditions: the Ethiopian Orthodox Tewahedo Church and the Eritrean Orthodox Tewahedo Church. At 81 books, it is the largest and most diverse biblical canon in traditional Christendom. 
Western scholars have classified the books of the canon into two categories — the narrower canon, which consists mostly of books familiar to the West, and the broader canon, which includes nine additional books. 
It is not known to exist at this time as one published compilation. Some books, though considered canonical, are nonetheless difficult to locate and are not even widely available in the churches' home countries of Ethiopia and Eritrea.
Narrower biblical canon.
Old Testament.
The Orthodox Tewahedo narrower Old Testament canon contains the entire Hebrew protocanon. Moreover, with the exception of the first two books of Maccabees, the Orthodox Tewahedo canon also contains the entire Catholic deuterocanon. In addition to this, the Orthodox Tewahedo Old Testament includes the Prayer of Manasseh, 3 Ezra, and 4 Ezra, which also appear in the canons of other Christian traditions. Unique to the Orthodox Tewahedo canon are the Paralipomena of Jeremiah (4 Baruch), Jubilees, Enoch, and the three books of Meqabyan.
The books of Lamentations, Jeremiah, and Baruch, as well as the Letter of Jeremiah and 4 Baruch, are all considered canonical by the Orthodox Tewahedo churches. However, it is not always clear as to how these writings are arranged or divided. In some lists, they may simply fall under the title "Jeremiah," while in others, they are divided various ways into separate books. Moreover, the book of Proverbs is divided into two books — Messale (Prov. 1–24) and Tägsas (Prov. 25–31). Additionally, while the books of Jubilees and Enoch are fairly well-known among western scholars, the 1st, 2nd and 3rd Books of Ethiopian Maccabees are not. While they share a common name they are completely different from the books of Maccabees that are known or have been canonized in other traditions. Finally, within the Orthodox Tewahedo tradition, 3 Ezra is called Second Ezra, 4 Ezra is called Ezra Sutu'el, and the Prayer of Manasseh is incorporated into the Second Book of Chronicles.
New Testament.
The Orthodox Tewahedo narrower New Testament canon consists of the entire 27 book Christian protocanon, which is almost universally accepted across Christendom.
Broader biblical canon.
In addition to the nine books discussed below, all of the aforementioned books of the narrower canon are also by definition part of the broader canon.
Old Testament.
The Orthodox Tewahedo broader Old Testament has one additional book: the Ethiopic version of the Book of Joseph ben Gurion or Yosëf wäldä Koryon, elsewhere called "Josippon", or referred to by its author, Pseudo-Josephus, categorizing its authorship as pseudepigraphical. The book is a history of the Jewish people thought to be based upon the writings of Josephus, in eight parts.
New Testament.
The Orthodox Tewahedo broader New Testament canon has eight additional books. These are the four books of Sinodos, the two divisions of the Book of the Covenant, Ethiopic Clement, and the Ethiopic Didascalia. Most of the literature herein would either be considered part of the writings of the Apostolic Fathers or part of the Ancient Church Orders.
Sinodos.
The Ethiopic canonical Sinodos are four books of church order traditionally attributed to the Apostles. They are as follows: Ser`atä Seyon (30 canons), Te'ezaz (71 canons), Gessew (56 canons), and Abtelis (81 canons). Much of the material contained within these books, with the exception of Ser`atä Seyon, is traditionally considered to be of Clementine origin. Other non-canonical parts of the Sinodos are included with these four books within the Ethiopic MSS.
The Book of the Covenant.
The Book of the Covenant, or Mäshafä Kidan, is counted in two parts. Part one has sixty sections and is mostly about church order. Part two is the sixty-first section, and is a discourse of Jesus Christ to his disciples in Galilee following his resurrection.
Ethiopic Clement.
The Ethiopic canonical book of Clement, or Qälëmentos, is distinct from the well known Epistles of Saint Clement—1 Clement and 2 Clement—as well as the aforementioned Clementine Sinodos and any other Clementine literature known in other traditions. It is a uniquely Ethiopic book in seven parts, purportedly by Peter to Clement of Rome.
Ethiopic Didascalia.
The Ethiopic Didascalia, or Didesqelya, is a book of Church order in 43 chapters, distinct from the Didascalia Apostolorum, but similar to books I–VII of the Apostolic Constitutions, where it most likely finds its origins.
Translation into English.
There is a project underway to translate the complete Ethiopian canon into English for the benefit of Ethiopian expatriates.
