Purpose – The purpose of this paper is to provide an overview of new citation‐enhanced databases and to identify issues to be considered when they are used as a data source for performing citation analysis.Design/methodology/approach – The paper reports the limitations of Thomson Scientific's citation indexes and reviews the characteristics of the citation‐enhanced databases Chemical Abstracts, Google Scholar and Scopus.Findings – The study suggests that citation‐enhanced databases need to be examined carefully, with regard to both their potentialities and their limitations for citation analysis.Originality/value – The paper presents a valuable overview of new citation‐enhanced databases in the context of research evaluation.

Looking for Information -- A Survey of Research on Information Seeking, Needs, and Behavior by Donald Case

Purpose – The purpose of this paper is to examine information seeking behaviour targeted to music information seeking by amateur musicians, accompanied with empirical evidence from a survey on a community concert band. While several studies in the literature have examined information seeking in the context of hedonic motives (e.g. entertainment oriented), music information can also be used for utilitarian purposes by providing amateur musicians the necessary tools to improve their skill and become better in their practice. Design/methodology/approach – A review of the literature on music information seeking and an empirical study on members of an amateur concert band are presented. The theoretical construct of the survey is informed by Wilsons’ macro model of information seeking behaviour. This is employed in order to understand information motives and needs, as well as obstacles in information seeking of musicians. Findings – Musicians seek information not only for entertainment but for educational purpo...

Music, Musicians, and Information Seeking Behaviour: A Case Study on a Community Concert Band

A non-linear index to evaluate a journal's scientific impact

The global recession which began in 2008 affected the entire world including the European economy, with some countries being influenced more than others. At the end of 2012 the Greek economy was encountering a fourth consecutive year of deep recession while pressures to cut expenses in all sectors were still growing and making headline news. Academic libraries, which are dependent upon state funding, were experiencing the consequences of constant and deep budget cutbacks during that period. After a review the literature on the impact of the economic crisis on academic libraries in Greece, as well as at the international level, this chapter describes the results of a survey of Greek higher education academic libraries about the consequences of the devastatingly harsh economic environment in which they currently, and probably will continue to, exist. A survey was conducted online with 25 out of the 37 academic library directors in Greece. After analyzing the survey results, the authors describe strategies to sustain services and resources and propose strategies to adjust to a new fiscal reality. These strategies include synergies and alliances that academic libraries can achieve with various agencies within their educational institutions and/or externally. While the results are limited to a small number of academic libraries in one European country, all types of libraries can utilize the strategies outlined in this chapter.

Responding to Crises with Alliances: evidence from an Academic Library Survey in Greece

The dramatic increase in the amount of content available in digital forms gives rise to large-scale digital libraries, targeted at millions of users. As a result, it has become a necessary to categorize large texts (documents). The paper develops a novel method where text categorization is achieved via a reduction in the original data information using numerical conversion of a symbolic expression and an onion layers algorithm. Three different semantic categories were considered and five texts selected from each category for submission to a text categorization procedure using the proposed method. The results and the statistical evaluation of this procedure showed that the proposed method may be characterized as highly accurate for text categorization purposes.
