registration One copy of any book printed after the Act came into force was to be submitted within one month of publication to the British Museum, at the expense of the publisher. The Bodleian Library, Cambridge University Library, the Advocates' Library and the Trinity College Library, Dublin, were all empowered to demand copies, which were to be delivered within a month of receiving the demand. A registry of copyrights was to be kept at Stationers' Hall, and an entry was to be taken as prima facie proof of proprietorship; an assignation of copyright recorded in the register was to be considered as having the force of a legal deed.

The Act extended throughout the British Empire. It was repealed by sections 36 and 37(2) of, and schedule 3 to, the Copyright Act 1911.

That your petitioner cannot discover himself to have done unlawfully in this his said labor of writing books, or to have become criminal, or have forfeited the law's protection thereby. Contrariwise your petitioner believes firmly that he is innocent in said labor; that if he be found in the long run to have
