  • 1. PLVN – ICT Special Interest Group Thursday 21 st July 2011
  • 2. Also known as
    • Discovery layer
    • Discovery service
    • Web scale discovery service
    • Resource discovery platform
  • 3. What is a discovery layer?
    • A discovery layer provides a single point of access to the full library collection across bought, licensed and digital materials. Typically, a single search box is offered alongside a range of other navigation features. (Lorcan Dempsey LITA Top Tech Trends 2011)
    • Discovery Layer: an application or service which sits on top of a library’s catalogue, electronic holdings and other records to provide a unified and modern experience
    • (Chris Keene, University of Sussex Library 2010)
    • To me, a Discovery Layer allows a user to search across a library catalogue (or several), an ebook platform (or several), and a source of articles (or several).  And incorporates the following:
      • Federated searching
      • Metasearching
      • Single host environment
      • (Mita Williams, Windsor Public Library, Canada, 2008)
  • 4. How does a discovery layer work?
    • Federated search
    • Indexing of databases
    • Expanded search options
      • Narrowing
      • Fuzzy logic – Did you mean….
  • 5. What a discovery layer is not?
    • A replacement to federated search
    • A ready made index to all your databases content (depending on your vendor)
    • The cure for all your catalogue ills
    • The way to get people to use the rest of your library website
  • 6. What it can do for you?
    • Better searching
    • Cross platform searching
    • Quicker results (depending on indexing)
