1, Digital libraries: challenges and influential work
Huge difference exists between providing access to discrete sets of digital collections and providing digital library services. To address this problem. information providers have to design enhanced gateway and navigation services on the interface and also introduce federation mechanisms to assist users to retrieval information through the distributed and heterogeneous information environment. However, the seamless federation access to information is still a big issues in digital library services.
The author introduce the OAI, however, OAI does not work in some environment. OAI is not a perfect one for harvesting information. In the future years, current standards have to be extended to offer more effective and efficient access to the distributed information environment.


2, Dewey Meets Turing
Librarians, computer scientists, and the Digital Library Initiative
This paper focuses on the relationship between librarians and computer scientists. I do feel the same way with the author. Different occupations have different opinions on digital library, sometimes it is difficult to negotiate among these opinions.


3. Institutional repositories: essential infrastructure for scholarship in the digital age
The author described the current developments in institutional repositories and tried to explain why these are so deeply and strategically important to the enterprises of scholarship and higher education. Institutional repositories is a powerful idea.
