All of OCLC’s WorldCat Heading Toward the Open Web Excited by the "resounding success" of the Open WorldCat pilot program, the management of OCLC, the world's largest library vendor, has decided to open the entire collection of 53.3 million items connected to 928.6 million library holdings for "harvesting" by Google and Yahoo! Search. A letter from Jay Jordan, president and CEO of OCLC, went out to members on Oct. 8. Currently, the Open WorldCat subset database contains about 2 million records, all items held by 100 or more academic, public, or school libraries—some 12,000 libraries all told. The new upgraded Open WorldCat program will automatically include all of the 15,000-plus OCLC libraries that contribute ownership information (holdings) to WorldCat, unless the library asks to have its holdings excluded. In January 2005, Open WorldCat will officially graduate from a pilot program to a permanent "ongoing program"; however, the database will be open for "harvesting" to Google and Yahoo! If Google and Yahoo!
Deep Web FAQ Click on these links to learn more about the Deep Web. The Deep Web is content that resides in searchable databases, the results from which can only be discovered by a direct query. Without the directed query, the database does not publish the result. Search engines — the primary means for finding information on the "surface" Web — obtain their listings in two ways. Thus, to be discovered, "surface" Web pages must be static and linked to other pages. The is a research, information sharing and management tool for organizations that accesses tens of thousands of Deep Web databases and Internet search engines. In the earliest days of the Web, there were relatively few documents and sites. What has not been broadly recognized is that information is now being published in a different means on the Web, especially for larger sites or for traditional information providers now moving their content online. As early as 1994, Dr. All of these sources can contribute to Deep Internet content.
An Investigation into the Deep Web - Maddie Morris The Deep Web is even more extensive and arcane than its cavernous name intimates, and it doesn’t help that a sea of misinformation surrounds it. This paper seeks to fulfill the need for an accurate, comprehensible guide to the Deep Web suited to both the interested layman and the tech maestro. A quick Google search will tell you that the Deep Web is any Internet database not indexed by search engines. This is true, but the more you look into it, the more complicated and insufficient said explanation becomes. The Deep Web can be divided into two halves: one that can be accessed through a typical Internet browser, be it Firefox, Chrome, or Safari, and one that requires special software, the most common being TOR, I2P, and Freenet. Let’s start with the former. Contrary to popular belief, Google is not God. You guessed it—the Surface Web is the Web we use everyday, the sites we can get to from Google, Yahoo, or Bing. You may be beginning to wonder why any of this matters. Pearce says:
Interactive online Google tutorial and references - Google Guide "Invisible Web" Revealed - SEW From The Search Engine Report July 6, 1999 Lycos and IntelliSeek, maker of the BullsEye desktop search utility, have teamed up to produce an index of search databases to help users find information that is invisible to search engines. The "Invisible Web Catalog" provides links to more than 7,000 specialty search resources. Users can browse listings, or Lycos will suggest appropriate databases within its own search results. This is a great new tool because there's lots of helpful information locked away in databases that can never be indexed by search engines. For instance, say you searched for "cancer." So to get the most out of the Invisible Web catalog, change your search strategy at Lycos. You can also browse the Invisible Web Catalog's listings by going to its home page. Lycos Invisible Web Catalog This takes you straight to the catalog. IntelliSeek WebData
Welcome to the Foundation for Intelligent Physical Agents In search of the deep Web When Yahoo announced its Content Acquisition Program on March 2, press coverage zeroed in on its controversial paid inclusion program, whereby customers can pony up in exchange for enhanced search coverage and a vaunted “trusted feed” status. But lost amid the inevitable search-wars storyline was another, more intriguing development: the unlocking of the deep Web. Those of us who place our faith in the Googlebot may be surprised to learn that the big search engines crawl less than 1 percent of the known Web. Beneath the surface layer of company sites, blogs and porn lies another, hidden Web. The “deep Web” is the great lode of databases, flight schedules, library catalogs, classified ads, patent filings, genetic research data and another 90-odd terabytes of data that never find their way onto a typical search results page. Today, the deep Web remains invisible except when we engage in a focused transaction: searching a catalog, booking a flight, looking for a job. “The U.S.
GreyNet International, Grey Literature Network Service Grey literature Grey literature is informally published written material (such as reports) that may be difficult to trace via conventional channels such as published journals and monographs because it is not published commercially or is not widely accessible. It may nonetheless be an important source of information for researchers, because it tends to be original and recent.[1] Examples of grey literature include patents, technical reports from government agencies or scientific research groups, working papers from research groups or committees, white papers, and preprints. The term "grey literature" is used in library and information science. The identification and acquisition of grey literature poses difficulties for librarians and other information professionals for several reasons. Generally, grey literature lacks strict bibliographic control, meaning that basic information such as author, publication date or publishing body may not be easily discerned.
