Summary Digital reference is an important research area with the potential to enhance information delivery to library patrons. The process of digital reference involves the challenges and problems of an interactive computer-mediated reference interview. Related studies of mediated online searching have identified the major tasks during a mediated online search. The search intermediary's tasks included gathering information on the information need, previous searches on the topic by the information seeker, search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and the number of topics to be searched. The information seeker's tasks include providing information to the search intermediary on their topic, discussing their previous information seeking and evaluating the online search output. Models of digital reference interviews need to include more complex information seeking behaviors, such as successive searching and multitasking. Further research is needed to extend our understanding of digital reference processes. 相似文献

AbstractVarious desalination methods had been used in the past to treat a large collection of archaeological iron objects. In order to establish whether desalination treatments had been effective, the condition of the objects was assessed and the data analyzed using statistical methods. It was found that objects which had been treated using desalination methods were less likely to re-corrode, and the conclusion was that the development of more effective techniques of chloride removal would be useful. 相似文献

ABSTRACT The author presents the state of metadata schemes today and discusses the idea of a “third way” between free-text searching and full cataloguing. He concludes that there is no such compromise and suggests that metadata schemes will have to incorporate controlled vocabularies and detailed designators if they are to progress, thus leading to a confluence that will be, in essence, a new form of traditional cataloguing. 相似文献

Abstract Google is the search engine of choice for most Internet users. For a variety of reasons, librarians and other expert searchers do not always use Google to its full potential, even though it provides capabilities not possible in traditional bibliographic databases and other search engines. Applying expert searching principles and practices, such as the use of advanced search operators, information retrieval strategies, and search hedges to Google will allow health sciences librarians to find quality information on the Internet more efficiently and effectively. 相似文献

ABSTRACTVibrations due to heavy construction work continue to be a major concern for museums. Although there has been an increase in research on the effect of vibrations on objects of cultural heritage in recent years, selecting measures to protect collections and remain open during construction work continues to be difficult because of a lack of data on what objects can actually withstand, the complexity of vibration loads, and the uniqueness of each situation. The major renovation of the Central Library in Liverpool, UK, which shared walls with the World Museum and Walker Art Gallery, both of which belong within National Museums Liverpool, showed how museums and other institutions can successfully deal with such situations. An integral approach was taken, beginning with an extensive risk analysis to determine which objects could remain on display, which needed extra protection and regular condition monitoring, and which had to be removed. The museums then negotiated a vibration protocol and action plan with the contractors, including continuous monitoring, and trigger levels requiring consultation or work stoppage. Vibration data were also stored and used for later analysis. This integral approach was successful in protecting the collections on exhibition, with only two incidents of reported damage directly related to vibrations. A combination of museum staff experience, excellent communications with the contractors, and some flexibility in defining vibration limits provided a successful recipe for both museums. The analysis of the vibration data using the basic engineering concept of the Palmgren-Miner rule, supports a more flexible approach to setting vibration limits based on recently published guidelines. 相似文献

AbstractThis paper describes the digital resources construction in China, such as e-books and e-journals, and the importance of e-learning for Chinese education. Knowledge objects are regarded as base elements in the microstructure of digital resources. The knowledge deconstruction and reconstruction process is proposed for creation and reorganization of knowledge objects that serve as the knowledge elements in teaching reference materials. Based on knowledge objects and the knowledge deconstruction and reconstruction process, the Digital Teaching Reference Book System (DTRBS) of Tsinghua University is designed and developed to provide the teaching reference book services in the platform of Web services. 相似文献

Ralph Waldo Emerson's theory of public address may be characterized as a rhetoric of provocation. Emerson did not see truth as encompassed by the human mind, set down in a book, or defended by logic. It is a state of mind, an attitude of searching for and listening to the voice within, the voice of God. The preacher‐orator cannot communicate truth directly to other men; he can only provoke them into searching for it on their own. The philosopher, orator, or preacher was, for Emerson, “only a more or less awkward translator” of ideas already in the consciousness of his audience. An orator functions as a “divining‐rod” to the deeper nature of men, lifting them above themselves and creating within them as appetite for truth. 相似文献

ABSTRACT Web-scale discovery services promise fast, easy searching from a single Google-like box, pleasing users and making library resources more discoverable. Some librarians embrace the concept of giving users what they have come to expect from Google, while others are concerned that this will “dumb down” searching and undermine information literacy. In this article we explore the potential impact of Web-scale discovery tools on information literacy, focusing particularly on undergraduate research skills. We review the existing literature and present findings and experiences from two mid-sized academic libraries that have adopted EBSCO Discovery Service as their library home page portal. 相似文献

Abstract Mounting digital images of art objects on a Web site is only the first step in providing patron access to such materials. Libraries and museums have a responsibility to provide not only high-quality digital reproductions but also high-quality access from an integrated library catalog with controlled vocabulary and consistent access points. While some digital collections may have excellent internal searchability and require no more than collection level cataloging in a library's OPAC, others may demand cataloging of individual components of the collection. A particular collection's significance, its potential audience, the types of access required, as well as factors such as its size and cohesiveness need to be considered before becoming locked into a specific Web designespecially when it is that of another institution. This paper examines several online library catalogs in which records for art objects as well as historical objects and natural history specimens have been merged, with varying degrees of success, and briefly addresses a modest proposal to catalog ceramic objects at the Ohio State University Libraries. The importance of consistent subject access in a merged catalog, regardless of the thesaurus or thesauri used, is stressed. Library consortia and bibliographic utilities may offer an economically appealing alternative for libraries that cannot design and construct their own digital libraries but these external organizations often have limited capability for-or interest in-modifying the design for a particular library and even less interest in cataloging the collections. Libraries, too, must be faulted for simply listing available electronic resources, either alphabetically or in broad subject categories, on a separate portion of their Web page and failing to provide full catalog records in their catalog. Finally, it is emphasized that the current debate over the viability of MARC 21 versus other metadata standards remains largely irrelevant to the importance of continuing to cultivate a monolithic online catalog, maintaining cataloging standards, and not mindlessly developing what amounts to a separate, rudimentary catalog solely for electronic resources. 相似文献

AbstractA very heavily corroded Egyptian bronze statuette of Amon was cleaned by handpicking and found to be composed of six separately cast parts: two elements of head, two arms, the torso with legs, and the beard. Such cases do not seem to be unusual but are rarely observed because of beautifully concealed joins. Technical details of the mechanical methods of cleaning are given and some critical comments included on chemical and electrolytic methods: it has to be remembered that cleaning is an irreversible process. Attention is also given to analytical problems in heterogeneous objects such as this. 相似文献

Abstract As library service providers for distance learners, we are constantly searching for ways to assist them in their use of library resources. Virtual (real-time chat) reference is yet another tool to utilize in reaching these students. While virtual reference has been around for several years and many libraries offer such services, as a medium-sized institution, Emporia State University took some time to move into providing such a service on a formal basis. Several issues, including staffing and funding, delayed entrance into this arena. It was not until a collaborative academic reference venture among several academic libraries in the state was proposed that the ESU library was able to offer this service. Advantages and disadvantages of the collaboration will be discussed, as well as lessons learned that can be applied to any collaborative project. 相似文献

AbstractA small but significant proportion of the archaeological iron objects in the British Museum collection have been problematic in that some of them have required repeated treatment. The deterioration of iron objects during storage was studied using microscopy, Raman spectroscopy, X-ray diffraction, scanning electron microscopy/energy dispersive X-ray analysis, X-ray fluorescence spectroscopy and ion chromatography. A total of 125 iron objects, including 56 from two British Roman sites and 69 from three Anglo-Saxon sites, were studied. Both surface corrosion and corrosion layers on polished cross-sections were investigated. The study revealed that the present condition of the iron objects varies; some are in a stable condition and others have been deteriorating, with pitting and weeping present on the surface. No treatment method had stopped corrosion for every object, although the alkaline sulphite treatment seemed to be more effective than the other methods. The results also showed that chloride ions can be present at the interface of the metal and inner corrosion layers. It is recommended that iron objects which have been mechanically cleaned without desalination treatments are kept in a dry environment to prevent further deterioration. 相似文献

Abstract This article presents an annotated list of career and employment web sites to assist librarians and job seekers with locating information on all aspects of career and job searching. General indexes to career and employment resources are provided, along with sites specializing in career fairs, resume services, relocation and newsgroups. The aim of this paper is to present stable, comprehensive, and well maintained sites that provide resources and services without charge. However, some sites that charge for services, such as resume evaluation and writing, have been included because they also offer links to other sites and information that could be useful to a job searcher. 相似文献

AbstractThis article reports on the results of an exploratory user-centered study that examined how technological advancements in natural language processing (NLP) such as the availability of multilingual information access (MLIA) tools impact the information searching behavior of bi/multilingual academic users. Thirty-one bi/multilingual students participated in a controlled lab-based user experiment in which they carried out two assigned tasks each on Google and WorldCat for a total of four tasks, and then completed a post experiment questionnaire. The captures from the experiment showed 86.7% of the participants using multilingual information access tools. Further analyses of the captures also showed that participants were more likely to use MLIA tools when the instructions for the task were stated in their native language. An independent samples t-test revealed that participants spent less time on their searches when they used MLIA tools. The study revealed considerable diversity in the information searching behavior of the participants, even within the same pair of languages, and even for the same user. Diversity was noted for instance, on which tasks MLIA tools were used and in how these tools were used. User-centered designed, personalized multilingual information retrieval (PMLIR) models could hold promise for best representing the information searching behavior of bi/multilingual users. 相似文献

SUMMARY Librarians are often hampered by the limitations of online catalog systems because of a lack of flexibility in how they present relationships among serial information objects and their bibliographic surrogates. Therefore librarians have to look outside the box and consider other methods for enhancing bibliographic clarity and access. They also have to be forward thinking and develop an information environment that is less encumbered by machine-imposed strictures such as linearity, polarization of viewpoint and visual constraint. 相似文献

Abstract Primo Analytics from two campuses of the California State University system has revealed that a dramatically low proportion of Primo searches originate from mobile devices. The current study focuses on usability concerns as one area that may be preventing students from searching the Primo mobile interface. The sample for this study includes students from two campuses with a variety of experience with library instruction and searching the library’s discovery system. Participants were given the same set of six common academic tasks to complete. Both mobile and desktop participants found three tasks relatively easy to complete. When there were differences in completion rates between the mobile and desktop users, the desktop users were overall more successful. No task was consistently difficult for desktop users to complete, while mobile users found two of the tasks very challenging to complete. Based on the findings, the authors make recommendations for improving the experience of mobile users. 相似文献

Abstract Many libraries use RSS to syndicate information about their collections to users. A survey of 65 academic libraries revealed their most common use for RSS is to disseminate information about library holdings, such as lists of new acquisitions. Even though typical RSS feeds are ill suited to the task of carrying rich bibliographic metadata, great potential exists for developing applications that can exploit metadata exposed to Web services via RSS. Using the MODS metadata format, entire catalog records can be seamlessly embedded in RSS 2.0 feeds. Existing tools, such as Library of Congress Java toolkits and XSLT stylesheets, can facilitate this process, while a new XSLT stylesheet may be used to create the RSS feeds complete with MODS records. As an example of the added functionality these MODS/RSS feeds can offer, records from a MODS-enriched RSS feed can be ingested into a non-RSS application such as Zotero. As more emerging library technologies use Web services architectures to handle data objects, the ability to syndicate catalog records will become more critical to providing innovative library Web services. 相似文献

ABSTRACTPreviously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO2 was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO2 decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present. 相似文献
