It is easy, talking to Clancy and his colleagues, to be swept along by their missionary passion. But Google's book-scanning project is proving controversial. Several opponents have recently emerged, ranging from rival tech giants such as Microsoft and Amazon to small bodies representing authors and publishers across the world. In broad terms, these opponents have levelled two sets of criticisms at Google.
   
    First, they have questioned whether the primary responsibility for digitally archiving the world's books should be allowed to fall to a commercial company. In a recent essay in the New YorkReview of Books, Robert Darnton, the head of Harvard University's library, argued that because such books are a common resource – the possession of us all – only public, not-for-profit bodiesshould be given the power to control them.
   
    The second related criticism is that Google's scanning of books is actually illegal. This allegation has led to Google becoming mired in (陷入) a legal battle whose scope and complexity makes the Jarndyce and Jarndyce case in Charles Dickens' Bleak House look straightforward.
   
    At its centre, however, is one simple issue: that of copyright. The inconvenient fact about most books, to which Google has arguably paid insufficient attention, is that they are protected by copyright. Copyright laws differ from country to country, but in general protection extends for the duration of an author's life and for a substantial period afterwards, thus allowing the author's heirs to benefit. (In Britain and America, this post-death period is 70 years.) This means, of course, that almost all of the books published in the 20th century are still under copyright – and the last century saw more books published than in all previous centuries combined. Of the roughly 40 million books in US libraries, for example, an estimated 32 million are in copyright. Of these, some 27 million are out of print.
   
    Outside the US, Google has made sure only to scan books that are out of copyright and thus in the "public domain" (works such as the Bodleian's first edition of Middlemarch, which anyone canread for free on Google Books Search).
