    Abstract
    The scope and characteristics of what may be considered the first three generations of automated Internet indexing systems are identified and described as to their methods of compiling their datasets, their search interfaces and the associated etymological metaphors and mythologies. These three are suggested to be: firstly, the Archie system for single keyword and regular expression searches of the file lists of anonymous ftp sites: secondly, the Veronica system for Boolean keyword in title searches of the world's gopher servers; thirdly, a range of software techniques jnown as robots and search engines, which compile searchable databases of information accessible via the WWW, such as the currently popular Lycos project at Carnegie Mellon University. The present dominance of WWW client software as the preferred interface to Internet information has led to provision of methods of also using the first two systems by this single interface, and these are also noted

    Abstract
    Search engine coverage relative to the estimated size of the publicly indexable web has decreased substantially since December 97, with no engine indexing more than about 16% of the estimated size of the publicly indexable web. (Note that many queries can be satisfied with a relatively small database). Search engines are typically more likely to index sites that have more links to them (more 'popular' sites). They are also typically more likely to index US sites than non-US sites (AltaVista is an exception), and more likely to index commercial sites than educational sites. Indexing of new or modified pages byjust one of the major search engines can take months. 83% of sites contain commercial content and 6% contain scientific or educational content. Only 1.5% of sites contain pornographic content. The publicly indexable web contains an estimated 800 million pages as of February 1999, encompassing about 15 terabytes of information or about 6 terabytes of text after removing HTML tags, comments, and extra whitespace. The simple HTML "keywords" and "description" metatags are only used on the homepages of 34% of sites. Only 0.3% of sites use the Dublin Core metadata standard.
