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. [For background information on the Open WorldCat pilot, see "OCLC Project Opens WorldCat Records to Google" at The euphoria over the success of the Open WorldCat project stems from the burst of usage statistics. Throughout the project phase, libraries outside the initial pilot group of 12,000 libraries asked to join, including 21 state libraries. If Google and Yahoo!
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. 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. Crawlers find web pages by following links on other web pages, and from those web pages they follow more links until they have catalogued, or indexed, a good portion of the Web to be displayed on Google. You may be beginning to wonder why any of this matters. Pearce says: Tigas 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. No, Lycos isn't automatically searching these databases when you perform a search, which some people have mistakenly assumed. 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.

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. Today, the deep Web remains invisible except when we engage in a focused transaction: searching a catalog, booking a flight, looking for a job. As new search spiders penetrate the thickets of corporate databases, government documents and scholarly research databanks, they will not only help users retrieve better search results but also siphon transactions away from the organizations that traditionally mediate access to that data. “The U.S. Every search query is a unit of desire.
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. Definitions[edit] The concept of grey literature has emerged since the 1970s. The U.S. In 2010 D.J. Towards a new definition[edit] The proposal was to add four attributes to the New York definition: Impact[edit]
