This article compares the usage of print monographs acquired through firm orders and approval plans to determine whether title-by-title book selection makes a difference. The circulation data of print monographs acquired in a four-year period were extracted and separated according to their acquisition methods. Usage data were analyzed according to the Library of Congress Classification system and library's three subject area groups (Humanities, Social Sciences, and Sciences). The results indicate that books acquired via firm orders had a higher circulation rate in almost all subject areas. The authors discuss how the findings can be used to inform future collection practices. 相似文献

Even though a substantial amount of the library materials budget may be allocated for standing orders, this method of acquisition is frequently not given the same attention as those used for traditional monographs and serials. This article describes some of the differences in standing order material, including their shared characteristics with both monographs and serials. It also reviews factors that make some standing orders a good candidate for an approval plan. The article also enumerates some considerations in vendor selection decisions, regardless of which acquisitions method is used. The author concludes that it is definitely time to assess how these materials are acquired and which type of vendor is used and to make decisions that extend our purchasing power. 相似文献

The first year of law school is chock-full of new experiences. Students can become overwhelmed in the face of so much change that they forget why they chose law school as a career path. They often lose sight of their end goal and need a touchstone to ground them back to their initial interests. Legal Research is the ideal first-year class to connect the acquisition of legal skills with interesting topics in a way that encourages students’ engagement in their present and future learning. By adding a student-selected subject context to their class, Legal Research instructors can incorporate contextualized learning and active learning techniques that improve student engagement and student learning. This article discusses the transformation of a generic, required, first-year legal research course into one that divides into four small (18–20 students) classes, each with one of four topics: patent, trademark and copyright, traditional practice, and social justice. In addition, it envisions future innovations to improve student engagement and student learning. 相似文献

University College Dublin became the first library in the Republic of Ireland to trial patron-driven acquisition (PDA) as a collection development tool in 2013. A total of 42% of UCD Library's book budget was allocated to the project, which included both electronic and print books. This article describes the twelve month project from the tender stage, through evaluation and selection of supplier, to the final money being spent. We analyze which disciplines spent the most money, and how usage of PDA titles compared to non-PDA orders placed in the same time period. Finally, we assess the impact of PDA on the library's workflow. 相似文献

Server selection is an important subproblem in distributed information retrieval (DIR) but has commonly been studied with
collections of more or less uniform size and with more or less homogeneous content. In contrast, realistic DIR applications
may feature much more varied collections. In particular, personal metasearch—a novel application of DIR which includes all
of a user’s online resources—may involve collections which vary in size by several orders of magnitude, and which have highly
varied data. We describe a number of algorithms for server selection, and consider their effectiveness when collections vary
widely in size and are represented by imperfect samples. We compare the algorithms on a personal metasearch testbed comprising
calendar, email, mailing list and web collections, where collection sizes differ by three orders of magnitude. We then explore
the effect of collection size variations using four partitionings of the TREC ad hoc data used in many other DIR experiments.
Kullback-Leibler divergence, previously considered poorly effective, performs better than expected in this application; other
techniques thought to be effective perform poorly and are not appropriate for this problem. A strong correlation with size-based
rankings for many techniques may be responsible. 相似文献

类目细分后测定核心出版社的方法,有助于采访人员鉴别学术性图书的质量,从而为国内法律类图书的采选提供客观、有效的依据。通过将法律类图书的类目进行细分,选取其中较为通用的10个类目,基于引文分析法和布拉德福区域分析法测出22家核心出版社,并对其在2004—2007年国内出版的法律类学术性图书进行引文分析发现,对一个法律类学术性图书核心出版社来说,其出版的所有法律类学术性图书不可能都是其出版强项。 相似文献

ABSTRACT This article discusses various models for teaching international and foreign legal research. In some law schools, international and foreign legal research is a semester-long course. In other law schools, international and foreign legal research is a component of an advanced legal research seminar or an international law course. Stefa-nie Weigmann presents an overview of teaching international legal research and describes her experience teaching in various formats. Kath-erine Topulos outlines some of the resources that are helpful for those who want to begin teaching foreign and international legal research. Jean Davis and Victoria Szymczak discuss teaching techniques and class activities for a semester-long course. 相似文献

We apply the test of Ijiri and Simon (1974) to a large data set of authors in economics. This test has been used by Tol, 2009, Tol, 2013a to identify a (within-author) Matthew effect for authors based on citations. We show that the test is quite sensitive to its underlying assumptions and identifies too often a potential Matthew effect. We propose an alternative test based on the pure form of Gibrat's law. It states that stochastic proportionate citation growth, i.e. independent of its size, leads to a lognormal distribution. By using a one-sided Kolmogorov–Smirnov test we test for deviations from the lognormal distribution which we interpret as an indication of the Matthew effect. Using our large data set we also explore potential empirical characteristics of economists with a Matthew effect. 相似文献

Faculty participation in book selection in academic libraries is considered a desirable goal, but one which can have pitfalls, even in a setting where acquisition funds are entirely controlled by the library. This article describes a successful cooperative book selection arrangement which makes use of a faculty library committee and subject bibliographers for book selection in both a traditional, closely-defined field (German literature and philology) and an interdisciplinary area (German studies). 相似文献

web中大量新闻网页、博客、电子邮件等非结构化信息中蕴含着大量的知识,对其进行处理以自动获得知识具有重要意义。目前,一些基于信息抽取等技术抽取简单关联关系的知识获取应用系统存在明显的局限性,本文引入Apache Stanbol——Apache下的一种从非结构化信息中自动获取知识的开源项目,它是一个为语义内容管理设计的模块化的软件集和可重用组件,旨在将传统内容管理系统（CMS）拓展为支持语义服务的语义内容管理系统（SCMS）,在此基础上,为改善搜索引擎关于内容的搜索、分类,实体消歧及语义化查询等带来帮助。 相似文献
