Commonplace books (or commonplaces) were a way to compile knowledge, usually by writing information into books. They became significant in Early Modern Europe.

"Commonplace" is a translation of the Latin term locus communis (from Greek tópos koinós, see literary topos) which means "a theme or argument of general application", such as a statement of proverbial wisdom. In this original sense, commonplace books were collections of such sayings, such as John Milton's commonplace book. Scholars have expanded this usage to include any manuscript that collects material along a common theme by an individual.

Such books were essentially scrapbooks filled with items of every kind: medical recipes, quotes, letters, poems, tables of weights and measures, proverbs, prayers, legal formulas. Commonplaces were used by readers, writers, students, and scholars as an aid for remembering useful concepts or facts they had learned. Each commonplace book was unique to its creator's particular interests.

The Italian peninsula, during the course of the 14th-century, was the site of a development of two new forms of book production: the deluxe registry book and the zibaldone (or hodgepodge book). What differentiated these two forms was their language of composition: a vernacular.Giovanni Rucellai, the compiler of one of the most sophisticated examples of the genre, defined it as a "salad of many herbs."

John Milton (9 December 1608 – 8 November 1674) was an English poet, polemicist, a scholarly man of letters, and a civil servant for the Commonwealth (republic) of England under Oliver Cromwell. He wrote at a time of religious flux and political upheaval, and is best known for his epic poem Paradise Lost.

Milton's poetry and prose reflect deep personal convictions, a passion for freedom and self determination, and the urgent issues and political turbulence of his day. Writing in English, Latin, and Italian, he achieved international renown within his lifetime, and his celebrated Areopagitica, (written in condemnation of pre-publication censorship) is among history's most influential and impassioned defenses of free speech and freedom of the press.

William Hayley's 1796 biography called him the "greatest English author", and he remains generally regarded "as one of the preeminent writers in the English language"; though critical reception has oscillated in the centuries since his death (often on account of his republicanism). Samuel Johnson praised Paradise Lost as "a poem which...with respect to design may claim the first place, and with respect to performance, the second, among the productions of the human mind". Though Johnson (a Tory and recipient of royal patronage) described his politics as those of an "acrimonious and surly republican".

David Garrick (19 February 1717 – 20 January 1779) was an English actor, playwright, theatre manager and producer who influenced nearly all aspects of theatrical practice throughout the 18th century and was a pupil and friend of Dr Samuel Johnson. He appeared in a number of amateur theatricals, and with his appearance in the title role of Shakespeare's Richard III audiences and managers began to take notice. Impressed by his portrayals of Richard III and a number of other roles, Charles Fleetwood engaged Garrick for a season at the Theatre Royal, Drury Lane. He remained with the Drury Lane company for the next five years and purchased a share of the theatre with James Lacy. This purchase inaugurated twenty-nine years of Garrick's management of the Drury Lane, during which time it rose to prominence as one of the leading theatres in Europe. At his death, three years after his retirement from Drury Lane and the stage, he was given a lavish public funeral at Westminster Abbey where he was laid in Poets' Corner.
