ABSTRACT Scopus is a new all-science abstracting and indexing (A&I) database. It is the result of a two-year collaboration with librarians and researchers from all over the world. Scopus covers over 14,000 scientific, technical, medical and social science titles from 4,000 publishers. It offers new sorting and refining features so that researchers can easily find and access more than 27 million abstracts and citations stretching back to the mid-1960s. This article recounts the development of Scopus from its inception in 2002 to its success in securing over 100 customers within weeks of its recent launch. The story is told by one of the librarians heavily involved in testing and shaping the product and by one of the Product Managers who built it. 相似文献

In this exploratory study, a community of inquiry framework was used to investigate students' perceptions of the efficacy and quality of online information organization and abstracting and indexing classes. It was found that participants valued not only the flexibility of online education, but also the instructor's timely engagement and reflection. Study participants emphasized the necessity of the instructor's frequent engagement through various modes of communication, such as virtual and face-to-face office hours and email. Participants' interest in asynchronous instruction mode was also observed. These findings are in line with previous studies emphasizing the importance of teaching presence in online classrooms. This study contributes to understanding students' perceptions of the quality of online learning and teaching. 相似文献
