The bill imposed fines on anyone who imported or traded in unlicensed or foreign books, required every book for which copyright protection was sought to be entered into the Stationers' Register, provided a legal deposit system centred around the King's Library, the University of Oxford and the University of Cambridge, but said nothing about limiting the term of copyright. It also specified that books were property; an emphasis on the idea that authors deserved copyright simply due to their efforts. The Stationers were enthusiastic, urging Parliament to pass the bill, and it received its second reading on 9 February. A Committee of the Whole met to amend it on 21 February, with further alterations made when it was passed back to the House of Commons on 25 February. Alterations during this period included minor changes, such as extending the legal deposit system to cover Sion College and the Faculty of Advocates, but also major ones, including the introduction of a limit on the length of time for which copyright would be granted.
