    Abstract
    Advances in the publishing world have emerged new models of digital library development. Open access publishing modes are expanding their presence and realize the digital library idea in various means. While user-centered evaluation of digital libraries has drawn considerable attention during the last years, these systems are currently viewed from the publishing, economic and scientometric perspectives. The present study explores the concepts of usefulness and usability in the evaluation of an e-print archive. The results demonstrate that several attributes of usefulness, such as the level and the relevance of information, and usability, such as easiness of use and learnability, as well as functionalities commonly met in these systems, affect user interaction and satisfaction.

    Abstract
    Evaluation is a vital research area in the digital library domain, demonstrating a growing literature in conference and journal articles. We explore the directions and the evolution of evaluation research for the period 2001-2011 by studying the evaluation initiatives presented at 2 main conferences of the digital library domain, namely the Association for Computing Machinery and the Institute of Electrical and Electronics Engineers (ACM/IEEE) Joint Conference on Digital Libraries (JCDL), and the European Conference on Digital Libraries (ECDL; since 2011 renamed to the International Conference on Theory and Practice of Digital Libraries [TPDL]). The literature is annotated using a domain ontology, named DiLEO, which defines explicitly the main concepts of the digital library evaluation domain and their correlations. The ontology instances constitute a semantic network that enables the uniform and formal representation of the critical evaluation constructs in both conferences, untangles their associations, and supports the study of their evolution. We discuss interesting patterns in the evaluation practices as well as in the research foci of the 2 venues, and outline current research trends and areas for further research.

    Abstract
    Digital library evaluation is a complex field, as complex as the phenomena it studies. The interest of the digital library society still remains vibrant after all these years of solidification, as these systems have entered real-life applications. However the community has still to reach a consensus on what evaluation is and how it can effectively be planned. In the present article, an ontology of the digital library evaluation domain, named DiLEO, is proposed, aiming to reveal explicitly the main concepts of this domain and their correlations, and it tries to combine creatively and integrate several scientific paradigms, approaches, methods, techniques, and tools. This article demonstrates the added value features of the ontology, which are the support of comparative studies between different evaluation initiatives and the assistance in effective digital library evaluation planning.
