  • Note that each bullet needs a click to appear on screen!! OpenLinking is FD’s OpenURL resolver. The OpenURL resolver takes metadata and matches it with locally held rules about where your electronic content is available from. It means that FDI have implemented the OpenURL standard in its draft form, to enable your users to link from a search result in ZPORTAL to digital conent. Not all content providers and e-journal sites you use will be OpenURL enabled. However, this does not mean that you cannot link to those sites. FD have developed a range of templates which specify the metadata required for a website. Content can mean a range of media - including journals, electronic full-text, the library catalog, Internet search engines and so on.
  • Note that individual mouse clicks are needed on this slide. Life before ZPORTAL and OpenLinking - the research process currently goes something like this - your users search a database or databases to find articles that may be useful for their term paper they find some useful records and then print them out or save them to a floppy they then go check the OPAC and find the item on the library shelves or go to the e-journal (if they can find it on your website or through the OPAC perhaps) they would then locate the volume and then the issue (in both e-journals and on the shelves) in the case of e-journals, they may then find that the library doesn’t have a subscription, or they aren’t allowed access but if they are lucky , then they may finally reach their destination - the article
  • This slide is on page “x” of your training manual as well as in the ppt slides. So what’s going on in the background? The user must be authenticated to use openlinking - this enables authorization to take place - does the user have appropriate access rights? From a search result, metadata is taken and passed to the OpenURL resolver - configurable rules are questions - can I find the ISSN? What services are available to this user? And how do I build the URL to that service, given the metadata I have from the search result? Following this provess, the user is offered a number of links and by following the links, they can access full-text or library catalogues.
  • OpenLinking is the final piece in the ZPORTAL jigsaw. Using openlinking you will be resolving “the most appropriate copy” issue. OpenLinking is FD’s solution for linking from a citation to the full-text or other appropriate website or service.

  • LAU CASE STUDY By Cendrella Habre Systems Librarian Lebanese American University chabre@lau.edu.lbJanuary 24, 2006 1
  • Outline Terminology Definitions Major developers and available systems Brief overview of LAU’s ZPortal Looking @ other ZPortal examples Advantages & disadvantagesJanuary 24, 2006 2
  • TerminologyNote: This technology started in 1999/2000 Library Portals Federated Search Engines Library Portlets Protocols/Standards/Set of rules:  Z39.50  OpenURLs (Z2Web) Link Resolvers (OL2)January 24, 2006 3
  • Definition (1) Portal is a web-based search tool Portal concept is often ambiguous and confusing Portal is a “buzzword” – inappropriately used Other terms used in the information community:  Metasearch  Metadata search  Parallel search  Broadcast search  Cross-database search  Search portalJanuary 24, 2006 4
  • Definition (2) “A library portal or a federated search engine is a discovery tool (a software actually) that enables a user to search using a single-search interface across certain websites, library catalogs, and databases of information resources to retrieve and integrate the results in a single presentation”January 24, 2006 5
  • Library Portals vs. Federated Search Engines Library Portals  It is certain that all Library Portals can search Z39.50 databases  Yet not all Library Portals can search currently available licensed databases. (Authentication problem for remote users) Federated Search Engines can search all Z39.50 and currently available licensed databases for both walk-in and remote users.January 24, 2006 6
  • Library Portlet The Library Portlet is a small search window found on any web page of a university, organization, institution, company, etc., which allows direct access to the online catalog and other resources available. This is a powerful and convenient library resources tool.January 24, 2006 7
  • Z39.50 A protocol that allows a computer to search collections of information on a remote system, create sets of results for further manipulation, and retrieve information; mainly used for bibliographic information. www.cs.cornell.edu/wya/DigLib/MS1999/glossary.html A set of rules governing the formats and procedures used by two computers to interact with one another. www.esls.lib.wi.us/glossary.html A standard that defines how computers search in library catalogues. The Library of Congress is the Maintenance Agency and Registration Authority for this standard, see http://www.loc.gov/z3950/agency/ www.lib.monash.edu.au/vl/glossind.htmJanuary 24, 2006 8
  • OpenURL A standard developed by NISO (National Information Standards Organization) It provides a uniform way for users to link directly from bibliographic citations (in non Z39.50 compliant databases) to fulltext articles available in online resources, websites, and other services for which a URL can be constructed It facilitates linksJanuary 24, 2006 9
  • Link Resolver A link resolver uses the OpenURL standard to create links to content, such as E-journals, library catalogs, Internet search engines, some ILL systems, bookshops, etc. In other words, when a patron finds a citation or reference to a specific article, this link resolver supplies the best available path to the content, anywhere in the library collection.January 24, 2006 10

  • Database Aggregators: MultiSearch (CSA) OVID Technologies and MuseGlobal (Dec. 1, 2004 announced delivery of a metasearch engine) More to come______________________________________________________ _ Few aggregators have integrating metasearching into their resources, e.g.:  ScienceDirect  JSTOR  GALE  EBSCOhost  WilsonWeb  Etc.January 24, 2006 14
  • Hosting Note All the above mentioned companies provide hosting services at their own sites to potential clients.January 24, 2006 15

  • How does it work? The user must be authenticated to The OpenLinking Resolver asks the following questions: use OpenLinking. 1. Can I match on ISSN? The user runs a 2. What services are available to this user? search. 3. How will I build the URL to go to each available service? The user clicks on the link and it is When these questions are answered successfully, the opened in another links are built and displayed to the user browser windowThe search result contains metadata -Journal title:Journal of management studiesISSN: 0022-2380Date/volume and issue data:Jul2002/Vol39/Issue 5Pagination: p.619 January 24, 2006 19

  • Advantages: Less time in searching: Several resources are searched at once Single one-stop web page Single interface (results) Tremendous increase in the usage of online resources, thus cost-effective Excellent tool for ILL/DDS Portal vs. Google Searching techniques are applied, e.g., Boolean operatorsJanuary 24, 2006 21
  • Disadvantages: No Arabic support Security: It involves the opening of some ports outside the university firewalls End-user overwhelmed with # of hits Continuous maintenance and update Unable to cover all licensed databasesJanuary 24, 2006 22
  • Conclusion Library Portals or Federated Search Engines enable you to search a world of informationJanuary 24, 2006 23
