Discovering the Next Generation of Library Search Paul Pival Public Services Systems Librarian ppival@ucalgary.ca David Brown Head of Systems dkbrown@ucalgary.ca Aaron Wood Metadata Librarian Assistant Head, Technical Services aawood@ucalgary.ca Alberta Library Conference 2010 Jasper Park Lodge, Jasper, AB April 30, 2010

  2. A discovery is said to be an accident meeting a prepared mind. Albert Szent-Gyorgyi

  3. Academic Digital Libraries of the Future: an Environment ScanLaw, Derek (2009) New Review of Academic Librarianship, 15:1, 53-67.

  4. What do our librarians think? • Really depends on the discipline • Most don’t teach it • They see improvement since launch • They think it’s better than Federated Search

  5. What do our users think?

  6. I found Summon easy to use

  7. I was able to find relevant information on my research topic

  8. I would recommend this search service to a friend or colleague

  9. If it was available in the future, I would start my research with Summon

  10. Are you…

  11. Getting local records into Summon • Things to think about.

  12. Kinds of loading • MARC records • Harvesting via OAI-PMH • XML files

  13. MARC Records • Unique record key • Linking back to Catalogue • Updating or deleting records • Local data not in Bibliographic record • Call number • Branch • Holdings

  14. Handling Additions and Deletions

  15. OAI-PMH • Better handling of additions and deletions • Is the meaning of the metatdata clear outside of its context? • How complete is harvested metadata?

  16. Web-Scale Discovery Problematic Yet Enticing

  17. University of Calgary’s metadata record counts in Summon: • Over 2,270,000 MARC records • Just under 16,000 simple Dublin Core records from its institutional repository (DSpace) • Over 79,000 simple Dublin Core records from its local digitized collections (CONTENTdm and an in-house developed system) • 3,931 records describing cultural objects from its museum collection • 268 RAD-compliant xml records representing archival holdings

  18. The Problem: An Unbalanced Scale Full text vendor xml records Local collection metadata records: MARC, DC, EAD, etc.

  19. Solution? Through considering what the user-oriented goals of unified discovery services are: • Facets  met through leveraging available metadata? • Increased access points with more detailed information on individual search results  met through merging metadata records for the same resource, i.e., normalization?

  20. The Importance of Facets? • ‘...facets help end users refine searches, navigate, browse and manage large results sets’ (Calhoun, Online Catalogs, v) • ‘More Intuitive Searching: less complicated initial searches, less pre-limiting, more post-limits via faceting...’ (Harper, 11) • ‘Improved search of catalog and local resources: keyword, facets, visualization’ (Burke, 28)

  21. MARC Mapping:

  22. Enhanced MARC Mapping:

  23. Eg., Content Type Facet

  24. Increased Access Points and Clarity MORE: • hypertext links to resources and supplementary information, • subject information, • tables of contents, • abstracts and summaries, • and any other details available

  25. Current Examples Primo OCLC (Harper, 20) (Calhoun , RDA and OCLC,10)

  26. Web-Scale Discovery Exert Pressure Collaborate Respect Standards Look both Within and Outside Libraries
