Records are exported from ILMS. New search service with Verity K2. Links to ILMS for info form circulation control.
Faceted browsing; also from home page (thus facets apply to complete collection).
Default sorting result set:
According to Sokvitne is the most common sort order is alphabetical and sometimes creation date of record is used. Alphabetical order is probably the default for public libraries and academic libraries prefer date. But since Google the user expects the most relevant items on top of the list. But what is relevant? For academic users recency is probably an important ingredient of relevancy. Other ranking criteria? Sokvitne mentions popularity (based on lending info), citations, …
According to Sokvitne, the user applies the principle of ‘satisficing’ in dealing with result lists. The user doesn’t read the list from beginning to the end but stops with the first result that is good enough.

Problem with a heterogeneous database that is a merger of other databases is the minimal set of shared facets.

the catalog has become for many students
a call-number lookup system, with resource discovery
happening elsewhere

This article describes the new catalogue of North Carolina State University (NCSU) Libraries. The technology used is Endeca’s Information Access Platform. This allows, e.g., for faceted searching; in this article it is called faceted browsing and Endeca calls it Guided Navigation. An assessment study is reported based on log analysis, analysis of search results and usability testing.

Remarkable is the short implementation timeline: only 5 months. A critical factor was the belief of the library staff that “not all issues, particularly “edge cases,”
(i.e., rarely occurring scenarios) must be resolved before
releasing a new service.“
