The Internet as a Digital Library 2 Introduction The use of the as World Wide Web a digital library is explained, along with its operation. As a digital library, it can be seen as a collection of digital objects and, equally, as the networked equivalent of a real-world library. The World Wide Web is a distributed system and, from this, the importance of storing the material in a standard way and the need to access it in a standard way can be explained. This allows the roles of HTTP and HTML to be made clear, in that one is its basic form of communication and the other the way of standardising the form of the material held by the servers. In addition, the fundamental importance of the client-server mode of communication is stressed. The World Wide Web is a multi-media system, transporting data and meta-data to give meaning to the data. It is shown that the World Wide Web, along with enhancements such as search engines, provides a digital library capable of meeting the general needs of information workers. Objectives At the end of this module, you should be able to: describe the operation of the World Wide Web, including the contributions of HTTP and HTML.; appreciate the role of multi-media in the World Wide Web; establish that the World Wide Web may, with the support available, be regarded as a multi-media library capable of meeting the requirements of information workers. Conventional Libraries, Digital Libraries and the World Wide Web In parallel with this unit, you should read also read relevant chapters from your textbooks. A conventional library is a more or less coherent and comprehensive collection of information: it so happens that the information is stored on paper. As a unified and comprehensive collection of information, the World Wide Web can also be seen as a library: the fact that the information is stored electronically in a digital format leads us to refer to it as a digital library.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
