文献提供和馆际互借是图书馆向读者提供的两种常规服务项目。在服务中图书馆常常会应读者或者其他图书馆的请求代为复制和传递本馆所藏文献资料,如该资料尚在版权保护期内,则该复制和传递行为将不可避免地会触及版权问题。本文从制定法和判例法两个方面对美国版权法和法院判决例中涉及图书馆合理使用和免责的法律规定及司法判例作一简要介绍。 Document offerings and interlibrary loans are two general services the library offers to readers. In service, libraries often copy and transmit the documents of their own library at the request of the readers or other libraries. If the materials are still under the copyright protection period, the copy and transmission activities will inevitably touch upon the copyright issues . This article gives a brief introduction of the legal provisions and judicial precedents concerning the rational use and exemption of libraries in American copyright law and court rulings from the aspects of statutory law and case law.
