Commonplace books that survive from the Tudor period contain a huge variety of texts, including letters, poems, medical remedies, prose, jokes, ciphers, riddles, quotations and drawings. Sonnets, ballads and epigrams jostle with diary entries, recipes, lists of ships or Cambridge colleges and transcriptions of speeches. Collecting useful snippets of information so that they could be easily retrieved when needed, or re-read to spark new ideas and connections, was one of the functions of a commonplace book. But the practice of maintaining a commonplace book and exchanging texts with others also served as a form of self-definition: which poems or aphorisms you chose to copy into your book or to pass on to your correspondents said a lot about you, and the book as a whole was a reflection of your character and personality.
