Open search refers to websites and search engines that are openly-accessible and free-to-use for the purposes of searching across the web. Although open searching is not defined, it can be thought of as any tool or search interface/website that makes it possible to search freely and openly on the web. Typically, these search tools do a very superficial search over the top layer of the web. For academic papers, there are several ways the open web can be searched. For example: there are two major tools used in the sciences and medicine, first, Google scholar and second, Scirus. In addition, proprietary databases such as EBSCO and OvidSP are widely used. Some content can also be found in tools such as ERIC and of course the free interface to Medline, PubMed. Is there one all-purpose search engine to search all freely-available literature? No, not on the open web or in a subscription-based database. Needless to say, this causes a major problem in cumulating the scholarly literature. How do academic librarians plan to deal with this problem? A good first step is to acquaint yourself with the range of open resources in searching listed below.

"Open access to open search in medicine? tools, issues and possible solutions"

  • open search gets to the idea of being able to search academic literature without barriers
  • naturally, there are many 'shades' of open ...(see shades of Open Access)
  • even the least open content locked in the deep web may be findable using open search tools
  • see related shades of Grey literature
  • metaphors: open sesame; key unlocking door; freedom; liberation; entry
  • findability is a problem in a web universe of one-trillion pages, searchable by keyword-only
    • metaphors: fragmentation; million little pieces; everything is miscellaneous
  • search is defining activity of web; search is not comparable to find

Issues

How will health librarians find materials on the web in the future? In the excitement of open access to research materials in biomedicine - due to open access journals, for example - health librarians should devote some intellectual energy to examining how articles will be found in the evolving scholarly search space. Do we plan to rely on Google scholar? Will commercial databases like OvidSP and EBSCO offer federated or meta-search options to search beyond their silos? How will we locate scholarly materials in institutional repositories worldwide? Will we expect users to engage in repetitive searching to find these materials? There has been some early discourse around the principles of web 3.0, and its role in improving findability in this uncertain OA universe - what kind of potential does the semantic web offer to academic librarians? Perhaps some as-of-yet unannounced academic search tool is in development at Yahoo to compete against Google scholar?

Background

When first released in late 2004, Google scholar caused a stir in academic circles as the first open search tool dedicated to searching the web's scholarly literature. The idea was so appealing, in fact, that the software giant Microsoft launched its own competitor a few short years later, in 2006, called Windows Live Academic Search. Academic search never caught on with the same excitement or approval of the Google brand despite offering a useful functional option for searchers. By 2008, due to less than stellar performance, Microsoft announced it would retire Academic Search, opting out of its book digitization project as well. For its part, GS has remained sui generis in the academic search space. Its primary impact seems to reside in its simple interface, cited by searching and offering access to content that might otherwise not be found. Some critics charge that Scholar has not improved much since its launch in 2004, and web statistics suggest its popularity may be dropping off with time. For many searchers, even in academia, Mother Google - with its ease-of-use, unprecedented reputation and speed - is a worthy alternative. However, for many librarians and scholars, GS is indispensable for finding grey literature and Open Access material.
