3 What were doing… Why? Variables and options ILS and the Discovery Layer Interface Decisions Are we there yet?

4 Whats it all about? Embrace change Work backwards Consider the user

16 Discovery Layer? Next Generation Catalogue? Discovery Layer ILS - circ Image s These s Vendor ILS – bib, holdings E-J Fed Search

17 About discovery From inventory to discovery (and back again) Keyword searching versus index browsing Relevance ranking: precision, recall and first page principle

18 Open Source or Vendor open source e.g. VuFind, eXtensible Catalog, SOPAC ILS vendors e.g. Primo (Ex Libris), Encore (III) other vendors e.g. Endeca, BiblioCommons AquaBrowser, OCLC, Serials Solutions

19 Local or Hosted, Customize or Not Local: –hardware/software infrastructure –some local configuration possible Hosted: –minimal local hardware/software –ideally a service to manage user generated content Either: data matters

20 Web 2.0 Why? –interaction with collections –reliance on peer and expert opinion –social search What? Where? How? –user generated content academic concerns, placement, web scale –usage logs, recommender systems

21 Summary: some factors to consider User experience degree of integration search intelligence extensibility Local (or consortial) capacity time and money

22 Sian Miekle University of Toronto

23 Introducing the Discovery Layer Data loading User experience Local vs.hosted solutions

24 Data loading decisions Should data be loaded in new system? Advantages: Self-contained interface Data available to functionality of new system Challenges: Shifting the data Synchronizing the data

25 Discover Layer Application ILS Build indexes 8.5M items6.4M bib records2.3M authorities144K MARC holdings Restart application Convert to XML for search & display Data transfer (nightly)

30 User experience: using facets

31 User experience: changing search model

32 User experience: feedback 169 comments, Sept 08 – Jan 09 2:1 in favour of the new interface 50 comments requesting features (26 ideas) –6 ideas based old search models 6 grads, 3 library staff –6 ideas for new features 4 grads, 2 undergrads, 1 library staff –14 ideas: functionality missed from old system 6 faculty, 12 grads, 12 library staff, 3 undergrads

33 Local vs. hosted solutions Time to think Flexibility –Content: BIP, web pages, other data repositories –Presentation: visual, multiple, changing Challenges –Infrastructure –Staff Shared local solution? –Share common tasks –Share resources

35 1. User interface choices & decisions 2. User feedback & behaviour

36 UI Choices: Basic Search Screen just a search box & go? include choice of search indexes? (fielded searching) include alpha as well as keyword indexes? include limiting at time of search?

37 Search n Go: UWO (Encore)

38 Search n Go: Queens N.Y. (Aquabrowser)

39 Search n Go & Limit by Collection: Vanderbilt (Primo)

40 Choice of Keyword Indexes: U of T (Endeca)

41 Choice of Keyword Indexes & Databases: Villanova U. (VuFind)

42 Choice of Keyword & Alpha Indexes: Florida State U. (Endeca)

43 Choice of Keyword & Alpha Indexes: McMaster (Endeca)

44 Choice of Keyword/Phrase Indexes & Limit by Format, Location: Waterloo (Primo)

45 UI Choices & Decisions Search, search within results, start over – Oh my!

46 Search Within Results; Search button; Start Over link

47 New Search button; Search Within Results button

48 UI Choices: defaults facets: open, closed or a mix? after a closed facet has been opened, keep it open? after a search, keep the previously selected index chosen, or return to the default?

49 UI Choices: facets which? hierarchical or flat? what to call them? display order order of values within facets: alpha or most hits at the top? all and or some or?

50 UI Choices & Decisions Search logic –match on any 1, 2, 3 terms, all terms? Display –how to display the full bib & item details Alpha indexes –how to display?

51 1. User interface decisions 2. User feedback & behaviour

52 McMasters Initial Implementation Spring 2007 usability testing feedback via Tell us what you think button in catalogue most feedback within first 3-4 months

53 Some interesting results from usability tests... only 1 of 5 subjects used the dimensions (oh no!) some subjects relied on type-ahead to complete all queries

54 User Feedback: Negative

55 Suggestions/Problems/Question s

56 User Feedback: Positive

57 Most-Used Facets, Jan.-Dec. 2008

58 Alan Bell University of Waterloo

59 The hope, the promise One search box to provide fast and convenient access to all of our resources, regardless of format –Enable access to our digitized cultural memory –Address disjointed library experience –Attempt to remain relevant to web savvy users –Provide Google-like relevance and react to challenges on the commercial internet

60 Considerations, challenges Existing OPAC features Becoming an aggregator –Can we ever get metadata/access to everything? –Native interfaces –A lot of data Controlled vocabulary cross walks Local modifications and needs Partners/Community and Collaboration
