美国通过立法与司法判例保护和限制作者的版权,创造性地丰富作品“合理使用”情形,实现了作品版权保护与知识流通的平衡。相较于美国,我国在图书馆版权“合理使用”方面差距明显,为此,本文建议我国应完善作品版权“合理使用”的规则,设立适应科技发展的数字版权细则,在司法方面保护图书馆的公共性服务职能,弱化图书馆过度承担的版权责任。 The United States, through legislation and judicial precedents, protected and restricted the authors’ copyright and creatively enriched the work “fair use ” to achieve a balance between copyright protection and knowledge circulation. Compared with the United States, our country has a clear discrepancy between copyright and “fair use” of the library. Therefore, this paper suggests that our country should improve the rules of copyright and “fair use” and set up the digital copyright rules that adapt to the development of science and technology. In the aspect of protecting the public service function of the library, we should weaken the library’s excessive responsibility of copyright.
