Web Design Trends in Academic Libraries—A Longitudinal Study

This study examines several key design elements of 37 academic library Web sites (members of the Association of Southeastern Research Libraries) and how they have changed between 2012 and 2015. While several studies have reviewed library Web sites looking for common design elements and content, the present work may be the first to look at the design elements of a large group of library Web sites over time. This study has two main goals: to present an objective analysis of the navigation and search interface designs at research university library Web sites, and to assess the usage of Web-scale discovery systems and content management systems in libraries. Other areas explored include when sites were most recently redesigned and whether sites have adopted a mobile-friendly, responsive design. Notable findings include a very high usage of Web-scale discovery systems, an increasing adoption of open source content management systems, and increasing implementation of responsive design. Also noted was a strong and growing standardization in navigation design. This study concludes with a review of the trends and discussion of current design patterns in academic library Web sites.     

高校图书馆读者流失问题分析

随着网络的发展,越来越多的读者使用网络搜索引擎作为获取信息服务的入口,许多高校图书馆都面临不同程度的到馆读者减少的问题。通过对高校读者使用信息资源情况的分析,笔者认为目前使用高校图书馆的读者人数并没有明显的减少,图书馆应该更多关注改进信息服务的方式,以适应新环境下读者对信息服务方式的要求。     

Affective Experiences of International and Home Students During the Information Search Process

An increasing number of students are studying abroad requiring that they interact with information in languages other than their mother tongue. The UK in particular has seen a large growth in international students within Higher Education. These nonnative English speaking students present a distinct user group for university information services, such as university libraries. This article presents the findings from an in-depth study to understand differences between the search processes of home and international students. Data were collected using an online survey and diary-interview to capture thoughts and feelings in a more naturalistic way. International students are found to have similar information search processes to those of home students, but sometimes face additional difficulties in assessing search results such as confusion when dealing with differing cultural perspectives. The potential implications for information service providers, particularly university libraries, are discussed, such as providing assistance to students for identifying appropriate English sources.

信息搜索用户检索式行为研究综述

[目的/意义]用户的检索式行为是用户信息搜索的重要环节,本文拟通过综述的形式对这些研究进行梳理,形成较为完整的综述。[方法/过程]通过对国内外相关文献的梳理,将检索式构建行为划分为检索词、检索式和会话层三个层面,以及词汇、语法和语义三个维度,对每个维度及不同维度之间的研究的区别与联系进行讨论,并对检索式的重构行为、检索式的质量和效果评估、以及影响用户检索式行为的要素等几个方面的相关研究进行总结。[结果/结论]已有研究对于检索式行为中的检索词和检索式的词汇研究较为丰富,未来需要增加对检索式的语法和语义的研究,以便深入理解用户的检索式构成特征。另外,关于检索式重构的类别和模式的自动识别的探索有所不足。在检索式的质量和效果评估方面,还需结合多种情境因素,更深入地研究易于用户理解和利于其搜索的检索式推荐模式。
