The Stationers' Register was a record book maintained by the Stationers' Company of London. This was a trade guild given a royal charter in 1557 to regulate the various professions associated with England's publishing industry, including printers, bookbinders, booksellers, and publishers. The company's charter gave it the right to seize illicit editions of published works and to bar the publication of unlicensed books, and allowed publishers to document their right to produce a particular printed work in the register, which thus constituted an early form of copyright law.
