File format obsolescence is a major risk factor threatening the sustainability of and access to digital information.While the preservation community has become increasingly interested in tools for migration and transformation of file formats,the National Library of Australia is developing mechanisms specifically focused on monitoring and assessing the risks of file format obsolescence.This paper reports on the AONS Ⅱ prpkect,undertaken by the National Library of Australia(NLA)in conjunction with the Australian Partnership for Sustainable Repositories(APSR).The project aimed to develop a software tool which allows users to automatically monitor the status of file formats in their repositories,make risk assessments based on a core set of obsolescence risk questions,and receive notifications when file format risks change or other related events occur.This paper calls for the preservation community to develop a co-operating file format obsolescence community which includes registries,software tool creators and end users to effectively curate digital content in order to maintain long-term access. 相似文献

National and international publishers have been depositing digital publications at the National Library of the Netherlands (KB) since 2003. Until recently, most of these publications were deposited in the Portable Document Format. New projects, for example the Web archiving project, force the KB to handle more heterogeneous material. Therefore, the KB has developed a quantifiable file format risk assessment method. This method can be used to define digital preservation strategies for specific file formats. The choice for a specific file format at creation time or later in the life cycle of a digital object influences the long-term access to the digital object. The evaluation method contains seven sustainability criteria for file formats that are weighed for importance. There seems to be consensus on the sustainability criteria. However, as the weighing of these criteria is connected to an institution's policy, the KB wonders whether agreement on the relative importance of the criteria can be reached at all. With this paper, the KB hopes to inspire other cultural heritage institutions to define their own quantifiable file format evaluation method. 相似文献

介绍各国数字资源收割技术的发展,如挪威、新加坡、丹麦等从法律上明确公共图书馆对数字资源进行收割和保存的职责;日本、韩国、美国等国都各自开发了对网络资源进行爬行和抓取的工具软件。并着重论述新西兰国家图书馆与英国不列颠图书馆合作开发Web Curator Tool,在收割质量保障、保存格式、授权管理等方面优点明显,但在图像资源收割和大规模任务执行等方面还存在不足。 相似文献

The article discusses the ambitious Web site and project Digitalna knji?nica Slovenije [Digital Library of Slovenia]. It encompasses periodicals, books, photographs, music scores, posters, maps, and sound recordings. Its stated goal is to provide both global access to, and long‐term digital archival preservation of, Slovenia's national heritage. The availability in the DLS of antiquarian books, periodicals, and other formats alongside full‐text digital versions of some very prominent current periodicals makes for an intriguing open access hybrid of public domain and copyright‐protected materials. The author explains how this has happened. 相似文献

In recent years, opinions have varied on which digital preservation strategy to follow. Although the digital preservation community has now embraced the idea of applying both emulation as well as migration in their strategies, emulation is still looked upon with skepticism due to its technical complexity and initial costs. As early as in 2004, the Koninklijke Bibliotheek - National Library of the Netherlands (KB) - and National Archive of the Netherlands acknowledged the need for emulation, especially for rendering complex digital objects in the future without affecting their authenticity and integrity. For these reasons, a project was started to investigate the feasibility of emulation by developing and testing an emulator designed for digital preservation purposes. In July 2007 this project ended and delivered a durable x86 component based computer emulator: Dioscuri, the emulator for digital preservation. 相似文献

国外高校图书馆电子书利用权益相关问题探究 总被引：2，自引：0，他引：2
电子书在国外高校图书馆的使用主要存在如下问题:①对于图书馆读者使用电子书的限制:对于浏览、打印、下载和传送文件的限制;数字版权管理的限制。②图书馆文献流通和馆际互借的限制:对于用户数量和用户类型的限制;对于流通的限制;对于以课程储备为目的的电子书使用的限制和对于馆际互借的限制; ③电子书阅读器在高校图书馆的借阅限制:专有软件和文件格式的限制;不能离线访问的限制;用户设备上的电子书存在被撤销的潜在可能。应对许可限制最直接的方法就是从供应商处获取不限制使用的电子书、与其他图书馆和联盟合作从为用户争取最大权益的角度出发与出版商谈判对图书馆界有利的许可条款,并尽量购买供应商提供可接受的条款的电子书,同时培养用户良好的电子书使用习惯。 相似文献

ABSTRACTThis paper explores the attitudes of librarians in post-Soviet Kazakhstan regarding their roles at the new National Academic Library of the Republic of Kazakhstan (NAL). Using ethnographic observation, interviews, and surveys of library staff (n = 24), we find that Kazakhstani librarians either sensed a “calling” to librarianship or “fell into” library careers given life circumstances, and value their library for its contribution to cultural preservation and digital access on a national scale. This pilot project presents NAL to an international community, sharing the voices of Russian- and Kazakh-speaking librarians to highlight the role of libraries in the development of the post-Soviet nation. 相似文献

As a part of the National Digital Information Infrastructure and Preservation Program (NDIIPP), the Library of Congress (LC), partnering with the Center for Technology in Government (CTG), launched an effort in 2005 to integrate state governmental entities into the national network to preserve born-digital information that is both significant and at risk of loss. The main theme that emerged from the efforts of LC, CTG, and the state and federal digital preservation community was the importance of partnership efforts and collaborative strategies for the preservation of state government digital information. Based on the findings of the initiative, this paper discusses challenges and opportunities regarding interorganizational collaboration and community building for digital preservation of state government information. Following the community of practice framework, it is recommended that a “state government digital information preservation community” be developed to facilitate collaboration across agencies and knowledge professionals in state governments. 相似文献

The Library of the Université Libre de Bruxelles and Editions de l'Université de Bruxelles (EUB), the University's publishing imprint, have recently agreed to collaborate to provide free online access to recent out‐of‐print books published by EUB. The e‐books are available on the Digithèque website, a collection of digital copies of printed books created by the Library. This initiative is valuable for the scientific community and the general public who can freely access the books online, for the authors whose books have been digitized and widely disseminated, and for the publisher whose collections become more visible on the Internet, thereby generating more traffic on its website and potentially increasing sales of its other books. Around 20 books have been made available online so far. This article describes the context of the agreement, how the collaboration operates, the options of file conversion vs. book scanning, issues relating to copyright and users' rights, how access is provided to the digital copies, and future collaborative projects of the Library and EUB. 相似文献

With funding from the National Library of Medicine HIV/AIDS Community Information Outreach Program (ACIOP), librarians at the University of Florida Health Sciences Libraries partnered with university and community groups to facilitate collaboration, develop new information resources, develop information-seeking skills, and raise general awareness surrounding HIV/AIDS risks, prevention, and treatment. This article describes the skills development elements of the project, including development and implementation of an HIV/AIDS information resource curriculum for health care providers, social services professionals, and public librarians within the project’s partner organizations. 相似文献
