copies of the Historia Ecclesiastica are of the m-type, while English copies are of the c-type. Among the c-texts, manuscript K includes only books IV and V, but C and O are complete. O is a later text than C but is independent of it and so the two are a valuable check on correctness. They are thought to have both derived from an earlier manuscript, marked "c2" in the diagram, which does not survive. A comparison of K and c2 yields an accurate understanding of the original c-text, but for the first three books, which are not in K, it is sometimes impossible to know if a variant reading in C and O represents the original state of the c-text, or is a variation only found in c2. One long chapter, book I chapter 27, is also found in another manuscript, Rh. 95 at the Zürich Zentralbibliothek; this is another witness to the c-text and appears to be independent of c2, and so is useful as a further cross-check on the c-text. The m-text depends largely on manuscripts M and L, which are very early copies, made not long after Bede's death. Both seem likely to have been taken from the original, though this is not certain. Three further manuscripts, U, E, and N, are all apparently the descendants of a Northumbrian manuscript that does not survive but which went to the continent in the late 8th century. These three are all early manuscripts, but are less useful than might be thought, since L and M are themselves so close to the original. The text of both the m-type and c-type seems to have been accurately copied. Taking a consensus text from the earliest manuscripts, Bertram Colgrave counted 32 places where there was an apparent error of some kind. However, 26 of these are to be found within a transcription from an earlier source, and it is apparent by checking independent copies of those sources that in such cases Bede copied the mistake into his own text. History of the manuscripts K appears to have been written in Northumbria in the late 8th century. Only books IV and V survive; the others were probably lost during the Middle Ages. The manuscript bears a 15th-century pressmark of the Abbey of Fulda. C, also known as the Tiberius Bede, was written in the south of England in the second half of
