Unfortunately, some of William's marginalia are affected by a trimming by a bookbinder in the 17th century. This is the only medieval manuscript in which Book Five survives in full although there are a handful of later copies. William continued to revise the text over the next decade or so, with many of the revisions removing potentially offensive remarks about his contemporaries. Copies were made of the manuscript prior to and after the revisions and subsequently several descendants of these as well. All together there are nineteen medieval versions of the manuscript that provide us with a complex yet large record of the history of the text. The first printed edition of the "History of the English Bishops" was produced by Sir Henry Savile in 1596. He used Cambridge University Library's MS Ff.1.25.1 as his source and so it contains only the first four books. The source manuscript itself was a descendant of British Library Royal 13 D V, itself a copy of Magdalen College, Oxford MS lat. 172.
