An investigation of 133 job advertisements for systems librarians in American Libraries in 1996‐1997 was conducted to examine the increasingly important role that systems librarians play in the ever‐changing information environment, and to identify the knowledge, skills and qualifications of systems librarians expected by employers in various types of libraries. The results show that although systems librarians in different types of libraries may play different roles and have different emphases in their duties, the responsibility and knowledge requirements for them are generally expanding. Systems librarians are not only technology experts but also managers and coordinators. Positions for systems librarians in most academic and public libraries require at least one year of work experience. Employers expect systems librarians to have a strong computer and network background. Over two‐thirds of the position in public and academic libraries and more than half of the openings in other libraries require MLIS/MLS degrees.

Purpose -This paper seeks to investigate how to use a web analytics tool to conduct deep analysis of users' web behaviors. This study aims to focus on examining whether the types of traffic sources and temporal fluctuation influence the web visitors' performance on the web portal of a K-12 resource inventory. Design/methodology/approach -One year's data were collected via the Advanced Segmentation function of Google Analytics. To compare visitors' behavior from different types of traffic recourses with the intervention of temporal effect, clickstream data of three visitor segments were collected. Findings -Traffic sources and temporal effect have been found to influence web site visitors' performance interactively. Search engines seemed good at bringing a significantly large amount of traffic to the eThemes site, but most visitors are likely "information encounters". However, visitors from direct traffic (bookmark/typed URLs) seemed to visit the eThemes site purposefully -stay for a long time on the site and view more web pages. Additionally, loyal users of the site seemed to employ the eThemes site as an everyday life information source. Originality/value -This study introduces a strategic approach to study and analyzes web site visitors' behavior longitudinally. The findings of this study contribute to loyal user behavior identification. Empirical evidence has been found to support the correlational relationship between traffic sources, the temporal factor, and Key Performance Identifiers of a site.
