当前,高校馆配中文电子书的市场供给由直接渠道中的内容出版商和间接渠道中的数字图书馆集成商、传统纸质书馆配商构成。高校馆配中文电子书市场存在着平台众多、整合困难,电子书格式、功能与呈现方式不一,标准的行业认可度和执行力不足,新书纸电同步率不高,定价偏低等诸多问题。高校图书馆界应增进与供给渠道商的沟通合作,发挥CALIS的桥梁纽带作用,加强电子书的阅读推广,培养师生成熟的版权意识,深入调研读者阅读行为,制订符合馆情的纸质书与电子书协同采访方针。 相似文献

Librarians offer a unique perspective on e-books: on one hand they collect these resources and train users as part of their jobs, while on the other hand, they may be users of e-books themselves. With recent increases in research expectations for Canadian academic librarians, this study aimed to discover: when librarians do research, do they use e-books and how often are they using them? This study examines the results of a survey of 392 academic librarians from across Canada. The survey generated data on librarians' use of, and attitudes towards, e-books. While a number of studies examine the use and opinions of e-books among other user groups, this study examines how librarians search for or use e-books differently than other user groups. Results will help librarians to improve their liaison work and make more informed collection development decisions at their own institutions. 相似文献

[目的/意义]学术谱系以知识传承的方式助推科学发展。研究知识传承特征,探索学术谱系传承模式及其学术产出影响效能,为探索人才成长规律及人才政策制定提供参考。[方法/过程]基于LDA主题模型,以遗传学领域谈家桢为核心的学术谱系成员发表的期刊文献为研究对象,对该谱系成员的研究主题进行抽取,借鉴生物学"遗传"与"变异"的概念,根据主题相似度将谱系成员划分为"遗传学者"变异学者"和"非遗传非变异学者",并对三种学者的学术绩效进行分析。[结果/结论]分析结果表明,谈家桢学术谱系内"遗传学者"和"变异学者"的学术绩效相对较高;"非遗传非变异学者"的数量占比最多,但学术绩效相对较低;"遗传学者"与"变异学者"在不同主题下的分布具有明显差异。 相似文献

Our library has previously investigated the potential impact the addition of contents notes on circulation. In a subsequent study, we found contents notes were the second metadata element most heavily linked to circulation (title was first). Since there has been a marked decline in the use of print resources at our library and a corresponding increase in digital resources, we wanted to know if the addition of contents notes to records for online streaming audio files would result in a similar increase in usage. After enhancing the records, we tracked usage for a period of three months. 相似文献

Librarians in Sweden are facing huge challenges in meeting the demands of their organisations and users. This article looks at four key areas: coping with open science/open access initiatives; increasing demands from researchers for support doing systematic reviews; understanding user experiences in Swedish health science libraries; and the consequences of expanding roles for recruitment and continuing professional development. With regard to changing roles, there is an increasing shift from the generalist towards the expert role. The authors raise the issue as to how to prepare those new to the profession to the changing environment of health science libraries. 相似文献

IntroductionWhile early commenting on studies is seen as one of the advantages of preprints, the type of such comments, and the people who post them, have not been systematically explored.Materials and methodsWe analysed comments posted between 21 May 2015 and 9 September 2019 for 1983 bioRxiv preprints that received only one comment on the bioRxiv website. The comment types were classified by three coders independently, with all differences resolved by consensus.ResultsOur analysis showed that 69% of comments were posted by non-authors (N = 1366), and 31% by the preprints’ authors themselves (N = 617). Twelve percent of non-author comments (N = 168) were full review reports traditionally found during journal review, while the rest most commonly contained praises (N = 577, 42%), suggestions (N = 399, 29%), or criticisms (N = 226, 17%). Authors’ comments most commonly contained publication status updates (N = 354, 57%), additional study information (N = 158, 26%), or solicited feedback for the preprints (N = 65, 11%).ConclusionsOur results indicate that comments posted for bioRxiv preprints may have potential benefits for both the public and the scholarly community. Further research is needed to measure the direct impact of these comments on comments made by journal peer reviewers, subsequent preprint versions or journal publications. 相似文献
