Development of an unified scheme

Digital libraries are widely used for organizing and presenting large collections of artifacts. However, as the digital libraries grow in size, it is becoming increasingly difficult for the user to find all the resources related to his topic of interest. It is labor intensive, time consuming and error prone to identify and link related materials manually. Thus it is important to develop automatic techniques to help the user discover and view the related resources that are available in the digital library. We have implemented an automatic interlinking mechanism for a music digital library system that spans across batch, online and on-demand phases. Since the task of generating the related links is resource and time intensive, distributing the whole process across these three phases significantly reduces the runtime overhead and improves the response time. This mechanism allows the system to display very large texts, with keywords identified and hyperlinked, with no perceivable delay to the user. Storing the artifacts in a structured manner and using the structural metadata to generate interlinkages allows us to create these links across diverse media like images, audio files, music scores, texts, etc. The implemented interlinking technique also scales well with a rapidly changing collection. The related links are displayed on demand, using AJAX technology. This allows the user to view these links without leaving the text, thus ensuring minimum disruption and continuity of action. We also have developed a generic interlinking framework which abstracts the domain independent logic for generating and displaying related links. This generic interlinking framework can be used by domain specific digital libraries to support interlinking of related resources.

This paper examines the role of library knowledge organization practices in supporting the social role of the public library through a discussion of the formation of the Dewey Decimal and Soviet Library-Bibliographic classifications. I show that in spite of significant differences in the ideologies motivating the ontological design of the classifications themselves, the methods and motivations behind creating such classifications were very similar, whether the location was late nineteenth century America or early twentieth century Soviet Russia. Both classifications are highly instructive as snapshots of thinking contemporary to their creation, and in the Soviet Union, library classification was construed as one more layer in the process of information control and indoctrination in Marxism-Leninism. Such a role was possible for these classifications because they were conceived of and first spread in a modern world, where the idea of a single and knowable truth was both acceptable and a worthy goal to pursue. The advent of postmodernism, with its emphasis on questioning monolithic myths, systems or ‘truths,’ has changed that attitude, and the advent of the Internet, search filters and personalized information has removed the library’s former monopoly as the only real purveyor of information available to the general public. In a world where uniting myths are neither needed nor wanted and information is at most of our fingertips, what role can the classification play? How can a modern classification organize a postmodern world? / text

Subject headings for works of fiction are one way to increase access to these books. Increased access should result in greater use for these books. Using a multi-branch, metropolitan public library, fiction books with subject headings were compared against fiction books without subject headings for overall use and circulations (use adjusted for time available to circulate). These same two categories were then compared to determine the affect of subject headings with respect to: fiction collection size, genre, and publication date for overall use and circulations.
