"In 2009, after a public appeal, the British Library purchased a manuscript 'Booke', which Captain Narbrough bought in 1666 and into which he subsequently entered his journals of his voyages and correspondence relating to them. The 'Booke' contains his own fair copy of the journal of his voyage through the Strait of Magellan and north to Valdivia in the Sweepstakes, 1669-1671. This is published here for the first time, together with an incomplete and somewhat different copy of the journal, held in the Bodleian Library, which was made for him by a clerk after he returned to England, and which was partially published in 1694"--Publisher's summary.
