    Abstract
    The success of the World Wide Web Shows that we can access, search, and retrieve information from globally distributed databases. lf a database, such as a library catalog, has some sort of Web-based front end, we can type its URL into a Web browser and use its HTML-based forms to search for items in that database. Depending an how well the query conforms to the database content, how the search engine interprets the query, and how the server formats the results into HTML, we might actually find something usable. While the first two issues depend an ourselves and the server, an the Web the latter falls to the mercy of HTML, which we all know as a great destroyer of information because it codes for display but not for content description. When looking at an HTML-formatted display, we must depend an our own interpretation to recognize such entities as author names, titles, and subject identifiers. The Web browser can do nothing but display the information. lf we want some other view of the result, such as sorting the records by date (provided it offers such an option to begin with), the server must do it. This makes poor use of the computing power we have at the desktop (or even laptop), which, unless it involves retrieving more records, could easily do the result Set manipulation that we currently send back to the server. Despite having personal computers wich immense computational power, as far as information retrieval goes, we still essentially use them as dumb terminals.

    Abstract
    A new design for the DDC allows for display of the schedules and indexes in a hypertextual browser which was originally designed for the more conventional thesaurus with BT-NT, RT and USE-UF relations. Features of the DDC which approxumate those relations and the presentation of the rich vocabulary found in the hierarchical structure, captions, index entries and notes are represented for the library user's perusal and choice before searching a library's holdings. By dragging and dropping parts from such a display into a search window, the search for bibliographic items can begin and revised painlessly. Information such as class numbers of subject headings for retrieved items can be dragged and dropped into the searchw indow of the Visual Dewey display window as it suits the user to review vocabulary or revise the search results. This seamless to-ing and fro-ing allows for a truly interactive and spontaneous search environment, with maximum assistance at point of need. 'File folders' exist for saving any Visual Dewey information, any retrieved items, etc.

    Abstract
    S R Ranganathan's ideas have influenced library classification since the inception of his Colon Classification in 1933. His address at Elsinore, "Library Classification Through a Century", was his grand vision of the century of progress in classification from 1876 to 1975, and looked to the future of faceted classification as the means to provide a cohesive system to organize the world's information. Fifty years later, the internet and its achievements, social ecology, and consequences present a far more complicated picture, with the library as he knew it as a very small part and the problems that he confronted now greatly exacerbated. The systematic nature of Ranganathan's canons, principles, postulates, and devices suggest that modern semantic algorithms could guide automatic subject tagging. The vision presented here is one of internet-wide faceted classification and retrieval, implemented as open, distributed facets providing unified faceted searching across all web sites.

    Abstract
    The World Wide Web and the use of HTML-based information displays has greatly increased access to online information sources, but at the same time limits the ways in which they can be used. By the same token, Web-based indexing and search engines give us access to the full text of online documents, but make it difficult to access them in any kind of organized, systematic way. For years before the advent of the Internet, lexicographers built weIl-structured subject thesauri to organize large collections of documents. These have since been converted into electronic form and even put online, but in ways that are largely uncoordinated and not useful for searching. This paper describes some of the ways in which XML-based Web services could be used to coordinate subject thesauri and other online vocabulary sources to create a "Thesauro-Web" that could be used by both searchers and indexers to improve subject access an the Internet.
