....by both the discipline they serve (computer science, aeronautics, physics, etc. and by the format of their holdings (technical reports, video, software, etc. A recent survey found over 10 existing or recent different WWW oriented digital library projects spanning over 5 different disciplines [8]. In short, each scientific community is hand crafting their own digital library infrastructure. Aside from the duplication of effort, there is a risk that each discipline will become less knowledgeable of other disciplines, as geographic balkanization gives way to electronic balkanization in ....

....12 conference papers, and 20 technical reports [32] If we consider this pyramid of publications (Figure 1) to be typical, then a journal article actually functions as an abstract of a larger body of STI. It is estimated that there are over 100,000 domestic technical reports produced annually [8]. The result is that even if there are 20,000 primary research journals [3] they do not represent the entirety of STI. These numbers do not include 1) confidential, secret, proprietary, and otherwise restricted reports; or 2) non report STI, such as Journal Articles Conference Papers Technical ....

....Interoperability Digital libraries are the topic of research in many scientific communities. However, DL projects are partitioned by both the discipline they serve (computer science, aeronautics, physics, etc. and by the format of their holdings (technical reports, video, software, etc. [Esler98]. Each scientific community is hand crafting its own digital library infrastructure. This uncoordinated development approach was adequate in the early stages of DL and WWW technology, but DL technology is currently included in the strategic planning of many institutions. A clear path for ....

....papers, while not justifying journal publication, and many ideas or feedback on previous work do not require lengthy papers to present. These ideas or feedback can be presented in technical reports, working papers, or conference papers far in advance of the corresponding journal publication [4]. In areas such as computer science, significant work is often presented in conferences and the journal publication, if at all, comes much later. These areas can be rapidly moving, and the time between conference and journal publication can be significant. The broader coverage that can be provided ....

....Although we do not expect accuracy comparable to humans, we do expect that learning techniques can provide useful predictions by analyzing the manner of citation and the usage of words in the sentences surrounding the citation. For example, if a citation occurs in a group of citations (e.g. see [1,3,4,7,11,14] ) then the classification Supporting Reference may be more probable. If a paper is cited several times in the same paper, then the citing paper may be more likely to be Followup Work . 7 Summary The World Wide Web has revolutionized the way that people access information. Researchers and ....

....for authors, researchers, and institutions alike. While a fully integrated, multi discipline scientific and technical information (STI) DL has yet to emerge, there have been a number of production quality DLs in use for several years, mostly segregated along institutional and discipline boundaries (Esler Nelson, 1998). NASA s digital library, the NASA Technical Report Server (NTRS) has grown since its beginnings in 1994 (Nelson, et al. 1995) NTRS today serves an important role in the distribution of scientific and technical information for the Agency. It provides a front end interface to 20 separate ....

.... or study [20] We term this the Pyramid of Scientific and Technical Information (STI) Figure 3) We argue that the traditional journal article, the common element in many DL projects, is often a mere abstract of a larger body of STI, most of which is informally archived or not archived at all [4]. Figure 3: The Pyramid of STI Another observation from NASA DL http log files is that a surprising number of people do not find the NASA and NACA publications via the NASA and NACA DLs. Since the full contents of the NASA DLs are browsable, both the abstract lists and the reports are indexed by ....

.... (avoiding the link rot and content rot so often associated with unstructured collections on the Web) Currently, however, there are numerous single domain digital libraries with neither uniform interfaces nor mechanisms for employing them in tandem outside their specific domain of expertise [8] We are developing an Undergraduate Digital Library Framework (UDLF) 12] specifically to address the problem of digital libraries in the undergraduate environment. We envision a process and an environment where course materials can be archived in a UDLF library. These generic course materials can ....

....variability has typically discouraged attempts to implement meta search engines. We have previously examined various digital library architectures and have found the distributed architecture with the contributors being the authoring organization or individuals as the most desirable architecture (Esler Nelson, 1997). There are two primary advantages to distributing information among multiple servers versus implementing one centralized information server: 1. Each information server is now responsible only for maintaining information local to an organization. 2. One canonical information server or database ....
