her death. The cornerstone of the foreign-language department came from the Polish–Lithuanian Commonwealth in the form of Załuski's Library (420,000 volumes), nationalized by the Russian government at the time of the partitions. The Polish-language books from the library (numbering some 55,000 titles) were returned to Poland by the Russian SFSR in 1921. Although Germany was only constituted as a state in 1871, the first national library was set up in the context of the German revolutions of 1848. Various booksellers and publishers offered their works to the Frankfurt Parliament for a parliamentary library. The library, led by Johann Heinrich Plath, was termed the Reichsbibliothek ("Reich library"). After the failure of the revolution the library was abandoned and the stock of books already in existence was stored at the Germanisches Nationalmuseum in Nuremberg. In 1912, the town of Leipzig, seat of the annual Leipzig Book Fair, the Kingdom of Saxony and the Börsenverein der Deutschen Buchhändler (Association of German booksellers) agreed to found a German National Library in Leipzig. Starting 1 January 1913, all publications in German were systematically collected (including books from Austria and Switzerland). Legal deposit and copyright The principle of legal deposit applies in some countries. In the United Kingdom, the Legal Deposit Libraries Act 2003 restates the Copyright Act 1911, that one copy of every book published there must be sent to the national library (the British Library); five other libraries (the Bodleian Library at Oxford University, the Cambridge University Library, the National Library of Scotland, the Trinity College Library, Dublin, and the National Library of Wales) are entitled to request a free copy within one year of publication. The international nature of the book publishing industry ensures that all significant English language publications from elsewhere in the world are also included. In the Republic of Ireland, the Copyright and Related Rights Act 2000 specifies that one copy of every book published is to be delivered to the National Library of Ireland, the Trinity College Library, Dublin, the library of the University of Limerick, the library of Dublin City University, and the British Library. Four copies are to be delivered to the National University of Ireland for distribution to its constituent universities. Further, on demand in writing within twelve months of publication a copy is to be delivered to the Bodleian Library, Cambridge University Library, the National Library of Scotland, and the National Library of Wales.
