A note at the beginning of the commonplace book records that ‘The Collection was commenced at an early Age, and consequently in the first Pages many Things are inserted which might as well, and without any injury to the Book, have been omitted.’ There are headings used throughout, including: ‘Love’. ‘Mediocrity’, ‘Laugh’, ‘Deluge’, ‘Liberty’, ‘Sleep’, ‘Bees’, ‘East India Company’, ‘Gold’, ‘Women, ‘Wit and Humour’, and ‘Impeachment. Sources quoted in the commonplace book include Shakespeare, Addison, Burney, Pope, Johnson, and Rousseau. Much of the material was written during Owen’s time at Trinity College and so many of the quotations have a strong connection to Cambridge, including ‘Song Imitated from Voltaire by Mr Rough, Trin. Coll. Cant.’
