Hi Malko and good morning to you. Thanks for taking the lead in establishing a clean slate to read and write on. Here is a response to me about the keyword search issue by my cousin in Ohio, who is majoring in Library Science: >. . .There is also an article from "Wired" magazine (from about 2 years ago) that I would want to send you that addressed the indexing problems of the Web - totally ignoring the contribution of library indexing systems to the world of organized information. Actually, the Dewey system is joined by the Library of Congress cataloguing system (and, in many cases) local library variations on Dewey and LC. In other words, Dewey is not the only system currently in use. Both Dewey and LC use subject headings as a form of indexing which is actually not the same as keyword searching. For example, if one were to search for Quantitative Reasoning as a keyword search, the response would be quite different than if one were to do a subject search. In certain databases, the second search might not give any hits but the searcher would be directed to use a different term; one chosen by the database designer to "capture" those terms related to the intellectual idea of reasoning with numbers. Keyword and subject searches can pull from different areas of the information (e.g. keyword from everywhere as in the title, the author, the content, the references); subject search may only pull from the content (e.g. an article defined as being "about" something). It's become very complicated to talk definitively about database search strategies but it is always safe to say that database designers, wherever they hawk their wares, can benefit from reviewing library practices. < EOQ My thanks to her for her informed response. It is amazing to me that library science has been largely ignored up to now. E-commerce will place great pressure on search engines to become the tool it needs to become in order to facilitate business. The fallout will be widespread improvement to the average person's use of the web. Perhaps Internet #2 will take the lead here. MOO Stan
