  2. What Is Federated Searching? • Searches across multiple databases across various disciplines • “One-stop shopping” approach • Attempt to make searches faster, easier and more comprehensive

  3. Why Federated Searching? • Large number of academic articles published per year • Need for libraries to “Google-ize” their resources to make them easily accessible • Increase ease-of-use for students • Migration of most academic material from print to electronic format

  4. Federated Search Providers • CSA Illumina (Scholar’s Portal) • EBSCO • ProQuest

  5. SFX and Federated Searching • The “link” between searches and library holdings • Acts as a means for students to check if an article is available, and in what format • Presents value-added content, such as links to citation software, Ulrich periodical directory, and linking to Blackboard

  8. Federated Searching • Advantages • Can search across various disciplines at one time using one interface (“Google approach”) • Opens up resources that students may otherwise overlook, such as articles in a discipline outside their field of study • Makes students more aware of the resources available at a particular university via SFX

  9. Federated Searching • Disadvantages • Absence of unified search terms, thesauri and vocabulary • Lack of precision as searches encompass various disciplines • Many results may be irrelevant to users, thus wasting time and effort and discouraging further searching • Useful for general, “shallow” searches but not for more in-depth searches in a given area • Problems with stable URLs and availability for articles from different providers

  10. Federated Searching • Hands-on example: attempt a search using a generic term, such as “development” • Terms can mean many different things in different disciplines

  11. Federated Searching: what’s next • U of T to roll out Endeca, which takes federated searching further • Will give users the ability to search article indexes and catalogue holdings simultaneously

  12. Federated Searching: the debate • Does federated searching save time and effort in searching? • Does it meet user needs by being a “one-stop” search? OR • Does it over-simplify the process? • Is federated searching limited because of the lack of thesauri and common search terms? • Does it lead to “good-enough” results, and not the best results?
