A Single Search Box Interface to the NCSU Libraries, Two Years Later

1,662

Published on

QuickSearch is a federated library search tool designed to quickly connect users to a variety of library collections, services and tools. Rather than replace existing dedicated discovery tools such as the catalog, electronic resource search, and subject portals, QuickSearch is designed to complement and increase use of these tools by directing users to them via an intuitive single search box interface.

    64. 64. Lessons Learned <ul><li>Library search behavior *is* diverse </li></ul><ul><li>Search logs confirm that when presented with a single search box on a library homepage, users search for a wide-range of resources, services, tools; they don’t assume a single library collection type (e.g. catalog, articles) </li></ul>
    65. 65. Lessons Learned <ul><li>There is high user demand for a simple way to find articles </li></ul><ul><li>Our Find Articles module gets a lot of use, particularly the “quick article search” link; libraries should be doing more to make the process of finding articles easier </li></ul>
    66. 66. Lessons Learned <ul><li>Subject recommendations (in current form) are not very popular </li></ul><ul><li>Although users frequently enter open-ended topical searches, they don’t seem to respond to our current implementation of subject recommendations; we don’t know why, yet </li></ul>
    67. 67. Lessons Learned <ul><li>Power law is in effect for library search </li></ul><ul><li>An exceeding small number of library resources account for a sizable percentage of all searches and clicks; it pays to make these high demand resources easier to find </li></ul>
    68. 68. Lessons Learned <ul><li>In terms of library search, we still have a lot of work ahead of us </li></ul><ul><li>Libraries spend enormous resources on acquiring, cataloguing, and licensing content in a variety of forms; we need to make it easier to access all of this information; we ought to know more about how people search </li></ul>
