台湾地区的国立中央图书馆台湾分馆、台北市立图书馆、台北县立图书馆、林口乡立图书馆均制定了馆藏发展政策。这些馆藏发展政策的内容包括政策说明、本馆简介、馆藏概述、馆藏资料选择、馆藏资料采访、馆藏维护、对外活动7个方面。我国大陆地区公共图书馆在制定馆藏发展政策时,应借鉴台湾地区的实践经验,研究并拟定政策编制指南,并在具体政策文件中突出电子资源建设和馆际合作等问题。 相似文献

PDA采购模式被应用于我国纸本图书的采购中,出现了以"你选书,我买单"为代表的"类PDA"采购模式,并且在规模、周期和经费占比等方面具有越来越大的发展趋势。文章通过对藏书建设的专业思维角度进行辨析,将PDA采购模式和"类PDA"采购模式进行对比,从藏书内容和藏书结构两个方面进行阐述,认为"类PDA"模式把图书馆的采购权开放给读者,虽然在一定程度上满足了读者的个性化需求,但是采购图书的质量难以保证,给馆藏体系结构带来隐患。图书馆应该从图书馆专业活动的视角,寻求文献社会化管理发展的专业方法,建立专业的"类PDA"采选机制,同时平衡"需求"和"价值"的关系,提升采访馆员的专业能力,以"多模式、分层次"方式优化"类PDA"采购模式,以此来助推图书馆藏书建设和发展。 相似文献

国外图书馆藏书发展政策面临的问题与走向 总被引：1，自引：0，他引：1
进入新世纪以来藏书发展政策在国外一些图书馆受到冷遇,其主要原因在于藏书发展政策没有及时反映信息环境的变化给藏书发展带来的影响。数字时代图书馆仍然需要制订藏书发展政策,而未来图书馆藏书发展政策的制订需要考虑数字资源可能涉及的设备、技术、知识产权及图书馆联盟等因素。 相似文献

Interlending Services: Trends,Languages, and use for Collection Development at North-West University
Siviwe Bangani Mathew Moyo Sabelo Chizwina 《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2013,23(3-5):157-179
This paper uses the bibliometrics methods to analyse the interlending service trends, language and collection development at the North-West University. The results show that despite some challenges, ILS services at the NWU decreased. More than 98.5% of all documents requested are in English language followed by Setswana and Afrikaans. Out of the 535 books requested by the Mafikeng Campus, 138 were added to the collection of the library. These results point to a need for academic libraries in Africa to adopt strategies for the development of African languages. The results support the continued use of ILS data for collection development purposes. 相似文献

The number of topics that a test collection contains has a direct impact on how well the evaluation results reflect the true performance of systems. However, large collections can be prohibitively expensive, so researchers are bound to balance reliability and cost. This issue arises when researchers have an existing collection and they would like to know how much they can trust their results, and also when they are building a new collection and they would like to know how many topics it should contain before they can trust the results. Several measures have been proposed in the literature to quantify the accuracy of a collection to estimate the true scores, as well as different ways to estimate the expected accuracy of hypothetical collections with a certain number of topics. We can find ad-hoc measures such as Kendall tau correlation and swap rates, and statistical measures such as statistical power and indexes from generalizability theory. Each measure focuses on different aspects of evaluation, has a different theoretical basis, and makes a number of assumptions that are not met in practice, such as normality of distributions, homoscedasticity, uncorrelated effects and random sampling. However, how good these estimates are in practice remains a largely open question. In this paper we first compare measures and estimators of test collection accuracy and propose unbiased statistical estimators of the Kendall tau and tau AP correlation coefficients. Second, we detail a method for stochastic simulation of evaluation results under different statistical assumptions, which can be used for a variety of evaluation research where we need to know the true scores of systems. Third, through large-scale simulation from TREC data, we analyze the bias of a range of estimators of test collection accuracy. Fourth, we analyze the robustness to statistical assumptions of these estimators, in order to understand what aspects of an evaluation are affected by what assumptions and guide in the development of new collections and new measures. All the results in this paper are fully reproducible with data and code available online. 相似文献

This article puts the need for writing a collection development manual in its historical context. It discusses the reasons for producing a collection development manual: to smooth out the functioning of the processing operation; to consider all collection development assumptions; to stimulate both the authors and the users of the manual to discuss important issues in collection development; to reduce bibliographer stress by specifying procedures for collection development: and to provide evaluation criteria for bibliographers. The article distinguishes two types of manuals: the training manual and the reference manual. The training manual provides the novice bibliographer with a comprehensive understanding of the materials selection environment: the structure of the subject field, the library holdings, collection usage patterns, the budget situation, the library's collection development policies, and the library materials market. The reference manual provides a compilation of internal policies and procedures to be consulted by bibliographers when such knowledge is required. It is suggested that a reference manual be organized around the following topics: materials selection, budgeting, purchase, review, and use. 相似文献

ABSTRACTWe argue the need to demonstrate the value of preservation services to institutions, the public and funders, because it matters conceptually and needs to be supported and validated. To address this imperative, improved and focused data capture and its use by collection managers is advocated as the necessary first step towards the development of an evidence-based culture for preservation services and synoptic decision-making, where evidence enables us to optimise the outcome of planning. To do so, we need tools that enable us to evaluate diverse preservation scenarios. We demonstrate the potential of emerging cross-disciplinary tools and protocols developed in the recent years such as attitude surveys, computational modelling and demographic modelling. These offer evidence that informs prospective preservation planning and, importantly, provides a credible evidence base for advocacy. These possibilities are discussed within the wider context of well-established preservation planning protocols that have shaped collection management for three decades, broadly characterised as retrospective. 相似文献
