King Charles II rested his hand on the Bible when he recited the oath at Westminster Abbey on Saturday.
Prof Campbell explained that he made the edits as he had wanted his version to be close to the original text of the King James bible, which dates back to 1611.
“Over the centuries the King James Version has been quietly updated, with spelling modernised and cross-references added. I decided to publish an edition that was as close to the original as possible, but in roman type, which is much easier to read than the black letter gothic type of the original,” he said, as quoted by the BBC.
“I therefore reproduced the original pagination and a text, with all its 350 misprints, that was line by line, word by word and letter by letter the same as the 1611 Bible,” he added.
The Archbishop of Canterbury commissioned Oxford University Press (OUP) to produce a special hand-bound edition, decorated in gold leaf, for the Coronation.
Prof Campbell had prepared the edition to mark its 400th anniversary in 2011 and was surprised when he got to know that it was chosen for use in this historic ceremony.
