The Online Catalog "Most integrated library systems, as they are currently configured and used, should be removed from public view." - Roy Tennant, CDL
What ILS Catalogs Do Well…(liberally stolen from Roy Tennant) • Inventory control: What and where • Known item searching
What ILS Catalogs Don’t do Well…(liberally stolen from Roy Tennant, and augmented by me) • Any search other than known item • Most Anything other than books (serials, e-resources, articles, digital objects) • Logical groupings of results (e.g. FRBR) • Faceted browsing • Relevance ranking • Sideways searching (suggestions, expansion of searches and search targets)
Endeca purchase decision • Lots of topical searches and poor subject access • Keyword gives too many or too few results – leads to general distrust • Misunderstanding of authority headings • No relevancy ranking of results • Needed more responsiveness (speed)
Endeca, et al Speed Relevance Ranking Faceted Browsing True Browsing (LC) Spell-checking Automatic stemming “Did you mean…” Unicorn / Web2 As if… Last-in / First-out Authority index links Query required Dictionary lookup only No No Pursuit of Features
Pre-Endeca Catalog Search • 6 search tabs • 14 radio buttons • 1-4 drop down boxes
Endeca Catalog Search • 3 search tabs • No radio buttons • 2 search boxes • Keyword search default

The library system pile • “Seams serve as perceptible boundaries that provide points of reference; without such boundaries readers get ‘lost at sea’ and don’t know were they are in relation to anything else; they can’t perceive either the extent of what they have or what they don’t have.” -Thomas Mann
Future Plans • Ongoing tweaks: • Continued usability testing; more bling • Relevance ranking algorithms & spell correction thresholds • Additional browsing options • Endeca 2.0 ideas • FRBR-ized display (using OCLC work identifier) • Natural language entry points • Patron-generated refinements (folksonomies?) • Enrich records with supplemental Web Services content – more usable TOCs, book reviews, etc. • The death of authority searching (not authority work!) • More integration with QuickSearch, other data repositories, and third-party discovery tools: pointing content outward • Using Endeca for more kinds of content
