Metasearching

• Searching two or more separate sources
  simultaneously
• Often includes
• Merged and deduplicated search results
• Ability to save/email/download citations
• Can include
• Relevance ranking

28
Why Metasearching?

• Only librarians like to search, everyone else
  prefers to find
• Libraries increasingly offer a staggering array
  of resources
• Google has increased user expectations and their
  impatience
• New technologies are offering a possible solution

29
Benefits

• For users one place to search, no need to learn
  multiple interfaces, other services more easily
  integrated
• For staff decreased need to lead users to
  individual databases and teach multiple
  interfaces
• What this replaces possibly a subject guide to
  databases, but does not replace any software
  component libraries currently have

Web 2.0
36
Web 2.0

• Web 1.0 client sends request, server sends HTML
  page, connection dropped, client renders page
• Web 2.0 a set of technologies that enables
  grabbing information dynamically from various
  sources and presenting it in a highly interactive
  way
• Technologies involved
• HTTP, HTML, etc.
• Web Services
• AJAX

37
Web Services SOAP or REST

• A method to exchange structured information
  (i.e., XML) between applications
• SOAP request is packaged up as an XML file or,
• REST request is packaged up as a URL with
  parameters http//oai.cdlib.org/?verbIdentify
• The response is always XML

38
Google Maps
39
Ajax

• A particular flavor of Web Services that uses
  Javascript, XHTML, and CSS in addition to XML
• Provides highly interactive interfaces without
  web page reloads
• Google Maps prime example, but rapid uptake

40
OCLC Live Search

41
Mashups

• Using other peoples data in a presentation you
  control
• Uses Ajax technologies
• The opposite of silo systems systems that can
  mix and match data from multiple sources you do
  not control
