The livery companies of the City of London comprise London's ancient and modern trade associations and guilds, almost all of which are styled the "Worshipful Company of..." their respective craft, trade or profession.
London's medieval guilds evolved into corporations responsible for training as well as regulating their respective trades, such as wage control, labour conditions and industry standards. Like most organisations during the Middle Ages, these livery companies were obliged to forge close ties with the Church of Rome (at least prior to the Protestant Reformation) by endowing religious establishments such as chantry chapels and churches, by observing religious festivals with hosting ceremonies and their well-known mystery plays. Most livery companies retain their historical religious associations, although nowadays members are free to follow any faith or none.
Most livery companies maintain their original trade, craft or professional roles; some still exercise powers of regulation, inspection and enforcement, while others are awarding bodies for professional qualifications. The Scriveners' Company admits senior members of legal and associated professions, the Apothecaries' Company awards post-graduate qualifications in some medical specialties, and the Hackney Carriage Drivers' Company comprises licensed taxi drivers who have passed the "Knowledge of London" test. Several companies restrict membership only to those holding relevant professional qualifications, eg. the City of London Solicitors' Company and the Worshipful Company of Engineers. Other companies, whose trade died out long ago, such as the Longbow Makers' Company, have evolved into being primarily charitable foundations.
The Worshipful Company of Stationers and Newspaper Makers (until 1937 the Worshipful Company of Stationers) (usually known as the Stationers' Company) is one of the Livery Companies of the City of London. The Stationers' Company was formed as an organisation in 1403; it received a Royal Charter in 1557. It held a monopoly over the publishing industry and was officially responsible for setting and enforcing regulations until the enactment of the Statute of Anne in 1710. Once the Company received its Charter, “the Company’s role was to regulate and discipline the industry, define proper conduct and maintain its own corporate privileges.”
Its members (Master, Wardens, Assistants, Liverymen, Freemen and Apprentices) are mostly involved with the modern visual and graphic communications industries which have evolved from the company's original trades. These include printing, papermaking, packaging, office products, engineering, advertising, design, photography, film and video production, publishing of books, newspapers and periodicals and digital media. The Company's principal purpose nowadays is to provide an independent forum where its members can advance the interests (strategic, educational, training and charitable) of the industries associated with the Company.
