Government Search Engines

Three hundred years ago, Jonathan Swift foresaw the cultural danger of relying on indexes to organise knowledge. He believed index learning led to superficial thinking. Swift was right and a growing of teachers and public intellectuals are coming to the realisation that search engines encourage skimming, light reading and trifling thoughts. Whereas subject classification creates harmony and encourages serendipity; indexes fracture knowledge into snippets making us stupid. Thanks to Google, the superficiality of index learning is infecting our culture, our society, and our civilisation.
Google did not invent the index. That honour goes to the 500 monks led by Hugh of St Cher who compiled the first concordance of the bible in 1230. Nor was Google the first to dream of indexing all of human knowledge. Henry Wheately had the idea in 1902 for a "universal index". And Google was not the first to cynically dump advertisements into the search-engine index. What makes Google unique is the extent to which it has, oblivious to the consequences, made a business out of commercialising the organisation of knowledge.

When To Use Invisible Web Resources

The InvisibleWeb consists of searchable information resources whose contents cannot be indexed by traditional search engines. These include databases, archived material, and interactive tools such as calculators and dictionaries. Since these resources are embedded within thousands of individual Web sites, they are not “visible” to the search engines of today. Even if a site containing a database is retrieved, the search engine is unlikely to take you to the database itself, requiring you to surf the site to find it. Beyond the scope of even the most popular search engines, this incredible wealth of information has been largely unexplored, until now.

When you need:

  • FindArticles, Bartleby, Thomas Register, Making of America, etc.more control over the ways to limit the search -- in a history database, you can restrict by period or continent, for instance, and in a patent database, you can search by years and by class number. A particular kind of content search engines don't do well with -- images, streaming video, etc. to search a narrower more selective universe -- kids' sites, news sites, web cams, government documents, maps, reference sources, full texts of books, etc.

"...let us save what remains: not by vaults and locks which fence them from the public eye and use in consigning them to the waste of time, but by such a multiplication of copies, as shall place them beyond the reach of accident."

CLOCKSS PROJECT- Controlled Lots Of Copies Keep Stuff Safe

CLOCKSS Project (1/23/06) A group of publishers, librarians, and learned societies have launched a community initiative employing the LOCKSS technology to support a large dark archive that serves as a failsafe repository for published scholarly content. Controlled LOCKSS (CLOCKSS), aims to provide assurance to the research community that a disaster, which would prevent the delivery of content, will not obstruct access to journal content. CLOCKSS content or the orphaned content would only become available after a trigger event, such as the material was no longer available from the publisher. In these situations, a joint advisory board, representing societies, publishers and libraries, will begin the process to determine if the content is orphaned and whether it should be made publicly available.

The Dewey Decimal system, is used by many public libraries. The college library uses the Library of Congress classification system.

Students at the K-12 level need to cope with research library collections at colleges, online databases, the core bibliographic research tools in academic libraries, and online journal aggregation tools that contain collections of full text journals and are also searchable like Journals @ OVID, JSTOR, MUSE, Lexis-Nexis,

EBSCO, one database provider even has an elementary level, middle school level and high school level database set for student use that many public libraries subscribe to.
