  5. 5. History of Discovery  How did we get here?  Federated Search  Catalog Layers – Local Discovery  Web-Scale Discovery
  6. 6. The 1st Discovery Service (~1901)
  7. 7. Cataloging at LC, 1910/1920
  8. 8. MARC & OPAC (1980 – 1995) Pros Cons  Users can search the entire physical collection quickly  Tight ILS integration  One place to search  Users can only search catalog  Metadata searching only  1968 – 50,000 MARC records in existence  1982 – Card catalogs disappear  OPACs appear in the library on a single desktop computer
  9. 9. Uncork those bottles…  1990’s - Electronic databases appear  Not part of the physical collection  They change often  Multiple tools needed for searching content  Students and faculty no longer know where to look  And the e-content just keeps on coming…
  10. 10. Federated Search Pros: Cons:  Single search box for all content  Currency of content  Speed  Many indexes  Multiple ranking algorithms  Larger result sets incomplete  Internet Traffic  Content provider traffic
  11. 11. Catalog layers Pros Cons  Single index for all local content  Speed  Complete result sets  Usually combined with fed search for e-content  Difficult setup and software updates  Not tightly integrated with ILS
  12. 12. Web-Scale Discovery Pros Cons  Search all content, one place  Single search box  Single index  Single Relevance Ranking  Speed  Bandwidth  Complete result sets  No local hardware  No local install  Not tightly integrated with ILS  Easier setup (vendor maintains index) This isn’t web scale management…
  13. 13. Resource Discovery Tools Working Group 8 member team- representatives from Cataloging, IR, IT, User Experience, ERM Charged in late December 2010 to find a new discovery layer-Interim report in March 2011; 3 products were chosen to trial; Final report generated in late July 2011 EDS went live in January 2012
  14. 14. Onsite demonstrations Conference presentations Conversations Literature and online research Vendor interviews Ethnographic study Product testing Vendor surveys/questionnaires/follow-up questions

  16. 16. Bootstrap UX http://www.txla.org/sites/tla/files/conference/hand outs/289BOOTSTRAP.pdf What is it? Short ethnographic projects 6-15 weeks in length. A small team, of four to six librarians is ideal. It is good to have a range of skills represented: librarians that are good at interviewing, solving problems, and doing project management. It is crucial to have a person that has authority to make service changes as a research team member.

  23. 23. Web-scale Discovery Product Selection  What should you look for in a product?  Each vendor may provide some, but not all, of the possible features.
  24. 24. Unified index or Federated searching Advantage of web-scale over federated searching:  Records from content providers are entered into a single index.  Search results are combined and relevance ranked as if they came from a single source following the same metadata organization. Is the web-scale discovery vendor providing that?
  25. 25. Unified index or Federated searching Vendors may:  Claim to not use federated searching, but results are NOT combined and relevance ranked independently of native database scheme.  Provide complementary federated searching (in addition to true unified index), in case  content is not covered by agreements with vendors or  users prefer functionality of native database interface  Use a grand unified index of all records and present a library’s individual holdings as a subset of the larger index.
  26. 26. Hosted by vendor or library Discovery product may be hosted:  on external vendor server, as SaaS (software as a service); customizations may be possible via:  tech support (online/voice/email);  administrator module: direct online changes by library.  ready widgets: may be added to available features;  APIs: allow certain functions/features to be coded.  on local library server, possibly with code-level access:  library can make extensive and unique customizations;  vendor updates not made automatically on local server;  code-level local version may cost more.
  27. 27. Content Coverage Providers covered:  Number and variety  Types: academic, business, popular literature, etc.  Formats: periodicals, newspapers, books, etc. Areas covered:  Strong/weak disciplines  Fit with your institution’s specializations Metadata depth of index:  Mostly title, author, pub. date, etc. or also abstract, full text?  Does vendor enrich records, e.g. w/ subject headings?
  28. 28. Institutional records  Loading records to discovery system from ILS and IR:  Frequency: daily / weekly / monthly / every 6 months?  Full ILS dump or incremental load of updated records?  Availability in discovery system: couple of days or weeks?  ILS & discovery system: how well do they work together?  Compatibility: sharing of similar standards  Conformity to shared standards: interpreting shared standards in the same way.
  29. 29. Fitting Local Practices  ILS  Discovery System E.g.: Displaying on-order records:  For all discovery vendors connectivity is attained through Z39.50 protocol.  ILS sends status info to discovery service via Z39.50 from MARC 926 $b.  How Rice catalogs record status: In Stacks: 926 $a FONDREN $b STACKS $c PS3563.C337 A44 1992 $d BOOK $f 1 On order: 926 $a FONDREN $c PJ25 .L36 2012 $f NONE  Local workflow: On order status is indicated in Status field instead.
  30. 30. Fitting Local Practices  ILS  Discovery System Solution:  Check beforehand if working solution can be reached for all factors involved:  protocol used by discovery service,  if/how protocol is used by ILS,  local cataloging practices for entering data into ILS .  Find workaround:  e.g., link to catalog for item status.
  31. 31. Example of on order item
  32. 32. Full-Text Linking Options Full texts native to discovery platform  Discovery service vendor is also content provider.  Discovery service vendor’s content is available directly through discovery platform. Proprietary external links  Discovery service vendor establishes linking protocol with individual content providers  Static linking is predictable, works as long as links remain unchanged  Links created one provider at a time: limited, but growing in scale OpenURL links  Link resolver checks library’s A-Z list and links to matching full text  Existing standard: scales across most providers  Dynamic linking can be fickle: no holdings; source/target formats different
  33. 33. Conditional Custom Links • Some records (e.g., books, audio, video, music scores) may not have enough metadata to populate and run link resolver. • Create custom link for problem formats to run search (e.g. title + author) in third-party index with good metadata for these formats (e.g., rice.worldcat.org). • Set up OpenURL in third-party index to run resolver &  get to desired item or  request item via ILL or document delivery service. • Result: every record in discovery service has link &  users can always get or request item  with no manual data entry;  Last resort, just Check for availability.
  34. 34. Check availability via third party
  35. 35. Customization Options  Default search method  Boolean / phrase (terms in results are separated by defined number of words)  Find all search terms / Find any search terms  Result display preferences  by data set (library’s catalog / IR records displayed before other indexes)  by selected indexes (delisting undesired indexes in admin module)  by type of full text links (native full texts, proprietary links, OpenURL links, etc.)  Interacting with other services using widgets / APIs  Display results from external sources (images from Flickr, videos from YouTube, results from Google Books, etc.)  Provide links to frequently-used content sources, such as LibGuides  Post custom messages or other text, such as Library hours or upcoming events  Faceting preferences (date, subject, format, ...); Visual display, etc.
  36. 36. Licensed e-journal content  Provided in A-Z list, which is a separate service linked to discovery service.  Indicates available “full-text records” to discovery service search filters.  May be used as the knowledge base for OpenURL link resolver.  If A-Z service is from a different company, content is updated in discovery service by periodic manual loads.
  37. 37. Changes to related services  Switching subscriptions to providers whose databases are indexed in discovery service.  Customizing external platforms involved in discovery process.  E.g.: http://rice.worldcat.org/  Streamlining text & enhancing graphically resolver menu page as OpenURL use is increased.
  38. 38. Enhanced OpenURL menu Matthew Reidsma, “jQuery for Customizing Hosted Library Services", http://matthew.reidsrow.com/articles/11 (accessed July 24, 2012)
  39. 39. Some other points to consider  Quality of customer service and technical support.  Number of sites with similar ILS and IR software that implemented – not just purchased – the service.  Degree of integration with vendor’s other services.  Availability and extensiveness of admin module vs sole reliance on vendor’s tech support.  Compatibility with your remote access software (proxy, VPN).
  40. 40. Some other points to consider  Possibility to search unlicensed content (catalog and IR) off site w/o prior authentication: “guest access”  Scoping by subsets for specific library branches, e.g. business  Exporting data: printing, emailing, downloading, RSS feeds, compatibility with citation management formats, etc.  Possibility for users to create personal accounts.
  41. 41. Some other points to consider  Availability of mobile version.  Usage data: search count over-representation (e.g. z39-50) vs. full-text retrievals; compliance with COUNTER protocol.  Cost: one-time, maintenance, training, multi-year contracts, other services included for free, etc.  Time required for implementation to be completed: weeks, months?
  42. 42. Lessons Learned  Difficult to ask all the right questions when dealing with unknown:  Develop a method for product search & know what questions to ask;  Trust the process.  Ask in detail: One detail may reveal more questions.  Assume as little as possible: check what you understand by asking.  Fight urge to find the ultimate product:  all solutions are imperfect;  redo product search every 2 – 3 years.  There will always be problems: make sure customer support is solid.
