馆藏数字化是数字图书馆建设的重要组成部分,馆藏数字化对图书馆的挑战主要是现实馆藏与虚拟馆藏,数字馆藏的长期保存与保护,资源共享与知识产权和数字馆藏的共建共享。作者认为,直面这些挑战,图书馆必须以全新的视角去审视馆藏数字资源的发展与变化。 Digitization of collections is an important part of the construction of digital libraries. The challenges of digital library are mainly the collection of real and virtual collections, the long-term preservation and protection of digital collections, the sharing of resources, the building and sharing of intellectual property and digital collections. In the author’s opinion, facing these challenges, libraries must take a completely new perspective to examine the development and changes of digital resources in collections.
