Google（谷歌）图书搜索是一种图书内容的全文索引目录，它能够帮助读者进行图书全文检索并且迅速地定位并找到他们希望购买的图书。读者在搜索结果中发现感兴趣的图书后，能够进行少量的图书内容浏览，如果想要买到全文书籍，可以通过在搜索结果页面上出现的出版社网站以及网上书店的链接方便的进行图书购买。
What is Google Book Search?
Search the full text of books to find ones that interest you and learn where to buy or borrow them.How does Google Book Search work?
Just do a search on Google Book Search or on Google.com. When we find a book whose content contains a match for your search terms, we’ll link to it in your search results. Click a book title and you’ll see, like a card catalog entry, some basic information about the book. You may also see a few snippets of text from the book showing your search term in context. If the publisher or author has given us permission through our Partner Program then you’ll see a few full pages from the book and if the book is out of copyright, you’ll be able to page through the entire book. In all cases, you’ll see links that lead directly to online bookstores where you can buy the book.
对作者和出版商而言，这意味着数以百万计的图书，其中包括不再出版的和版权已公开的图书，能够立即被读者找到并且购买！Google（谷歌）图书搜索就象一项免费的营销计划：从理论上讲，它在保护版权的同时，极大地拓宽了全世界每一部图书的潜在读者群。
