right to reprint works falling outside the protection of the Statute of Anne. The Scottish booksellers argued that no common law copyright existed in an author's work. The London booksellers argued that the Statute of Anne only supplemented and supported a pre-existing common law copyright. The dispute was argued out in a number of notable cases, including Millar v. Kincaid (1749–1751) and Tonson v. Collins (1761–1762). A debate raged on whether printed ideas could be owned and London booksellers and other supporters of perpetual copyright argued that without it scholarship would cease to exist and that authors would have no incentive to continue creating works of enduring value if they could not inherit the property rights to their descendants. Opponents of perpetual copyright argued that it amounted to a monopoly, which inflated the price of books, making them less affordable and therefore prevented the spread of the Enlightenment. London booksellers were attacked for using rights of authors to mask their greed and self-interest in controlling the book trade. When Donaldson v Beckett reached the House of Lords in 1774 Lord Camden was most strident in his rejection of the common law copyright, warning the Lords that should they vote in favour of common law copyright, effectively a perpetual copyright, "all our learning will be locked up in the hands of the Tonsons and the Lintots of the age". Moreover, he warned that booksellers would then set upon books whatever price they pleased "till the public became as much their slaves, as their own hackney compilers are". He declared that "Knowledge and science are not things to be bound in such cobweb chains." In its ruling the House of Lords established that copyright was a "creature of statute", and that the rights and responsibilities in copyright were determined by legislation. By confirming that the copyright term (that is the length of time a work is in copyright) did expire according to statute, the Lords also affirmed the public domain. The Donaldson v Beckett ruling confirmed that a large number of works and books first published in Britain were in the public domain, either because the copyright term granted by statute had expired, or because they were first published before the Statute of Anne was enacted in 1709. This opened the market for cheap reprints of works from William Shakespeare, John Milton and Geoffrey Chaucer, works now considered classics. The expansion of
