The bundle of functionality encapsulated in the library catalog is an artifact of a particular phase of library operations. We are now seeing a move to a different model where discovery needs to happen in a variety of network environments. This means that the library has to think about reconfiguring its systems and services. It becomes important to think about how to disclose their offerings into the places where users are.

Moving to the network level:discovery and disclosure Moving to the network level: discovery and disclosure Presentation Transcript

  • Moving to the network level: discovery and disclosure Lorcan Dempsey ALCTS ALA Midwinter, Seattle January ?? 2007
  • The network rewrites behaviors
  • A few things….
    • Workflow and Attention
    • Aggregation of demand and suppy: the long tail
  • ~18 months old No FaceBook, MySpace Library?
  • University of Minnesota http://www.lib.umn.edu/about/mellon/KM%20JStor%20Presentation.pps
  • Database > website > workflow Prefabricated (e.g. CMS) Self assembled digital identity Netvibes, onfolio, my yahoo, myspace, RSS aggregator, …
  •  
  • Workflow
    • Then
      • Users built workflow around the library
    • Now
      • The library must build its services around user workflow
    Get into the flow Disclose into other environments
  • Attention
    • Then
      • Resources scarce, attention abundant
    • Now
      • Attention scarce, resources abundant
    Competition for attention
  • Long tail information providers Systemwide efficiences
    • Aggregation of supply
    • Unified discovery
    • Low transaction costs
    • Aggregation of demand
    Impact?
  • Libraries and the long tail dynamic
    • Aggregate supply?
      • 1.7% of circulations are ILLs
      • (60% of aggregate G5 collection owned by one library only)
    • Aggregate demand?
      • 20% of collection accounted for 90% of use
      • (2 research libraries over ~4 years)
    Each reader his/her book Each book its reader
  • The Library Long Tail (using holdings as measure of popularity) Note: All statistics are preliminary and subject to change. Final report forthcoming soon. Number of Holdings Items ranked by system-wide popularity “ Head” “ Long Tail” Head: Top 10% of WorldCat records (ranked by holdings) account for 80% of total WorldCat holdings Long Tail: Bottom 90% of WorldCat records (ranked by holdings) account for 20% of total WorldCat holdings Figure not drawn to scale; for illustration purposes only
  • ILL and the Long Tail ( FY 2005 OCLC ILL transactions) Note: All statistics are preliminary and subject to change. Final report forthcoming soon. Number of Holdings Items ranked by system-wide popularity ~75% of ILL requests were directed at the “Head” ~25% of ILL requests were directed at the “Long Tail” By comparison, Chris Anderson ( The Long Tail, 2006) reports: Amazon: ~ 25% of sales from the “long tail” Netflix: ~ 20% of sales from the “long tail” * Question: are current ILL systems adequately supporting demand for the library long tail?
  • For many years, Chinese people cited a proverb: if the wine smells really wonderful, customers will come in spite of the length of the lane .
  • The network rewrites the library: discovery and disclosure

  • Discovery: focus on catalog with some related …
    • Local Discovery Environments
    • Shared Discovery Environments
    • Syndicated Discovery Environments
    • Leveraged Discovery Environments
  • Local Discovery environment
    • Some (not necessarily aligned) motivations
      • Make data work harder
      • Integrate access to locally managed resources
      • Escape from ILS limitations
    • NCSU
    • Rochester
    • SOLR
    • Worldcat 2.0
    • Primo
    • Encore …

  •  
  • Some remarks
    • How does MARC data play with other data
      • Subjects, authors, ..
      • Historic investment in structure?
    • Duplicate cost?
    • Relationship to Metasearch?
  • Shared discovery environment
    • Increase impact
      • Create gravitational pull
      • Aggregate demand and supply
    • Reduce costs
  •  
  •  
  • Some comments
    • Integration of discovery to delivery becoming essential
    • A move to shared environments seems more likely with increased ability to ‘view’ different levels
    • Increased gravitational pull: greater use of collections
      • Growing evidence
  • Syndicated discovery experience
    • Syndicate data or service or links
  •  
  •  
  •  
  •  
  •  
  •  
  • Syndicating services
    • RSS
    • Portlets
    • APIs, Protocol-based
    • Projects
      • Sakailibrary
    Not as rapid as one might expect?
  •  
  •  
  •  
  • Some remarks
    • Syndication of data now common among data providers
    • Routing issue for non-unique materials
      • Resolution
      • Worldcat
    • Libraries exposing licensed content holdings interesting
      • Google Scholar
    • Service disclosure less common
      • APIs
      • Web services
      • Portlets
      • HTML fragments – ‘search boxes’
      • Toolbars
      • Widgets, extensions, …
  • The Leveraged discovery experience
    • In some ways the most interesting
    • Use another discovery service to connect back to your resources
    • Compare to the situation with article databases and resolvers
  •  
  •  
  • Click – look in OCLC Resolver Registry – pass through to the relevant library
  • Some remarks
    • Some of these are toy-like now, but indicate a direction
    • Increased capacity to ‘sense’ structure (microformats) will improve ability.
  • So ….
    • The library website is not the front door
      • We need to connect multiple discovery environments to library fulfilment options
      • We need to put library resources in users’ workflow
      • We need to place library resources in places which aggregate demand
    • Need more robust machine interfaces for the ILS so that we can put its functionality in other places (medium term)
  • And OCLC ….
