The organization of the digital library.

As digital information proliferates and the difficulties of managing it threaten to overwhelm traditional publication and information delivery processes, new visions of a digital library are forming. Exactly what a digital library is and how it is to be organized have not yet been determined, and bibliographic organization of digital information has not been sufficiently addressed. Bibliography is the systematic description or classification of writings or publications considered as material objects. In today's digital world, such material objects may no longer be relevant, but the need for systematic description remains. The important issue is not whether digital bibliography is needed but, instead, whether or not existing bibliographic techniques are appropriate for this new media. A second issue is the location of the responsibility for a new digital bibliography. Does it rest with medical informaticians, often the producers of this new digital information, or with librarians, traditionally the classifiers of information? Developments in both medical informatics and medical librarianship indicate a need for greater collaboration between these specialties in order to achieve their common purpose--the creation, classification, and dissemination of scholarly information.

A distributed, collaborative, structuring model for a clinical-guideline digital-library.

The Digital Electronic Guideline Library (DeGeL) is a Web-based framework and a set of distributed tools that facilitate gradual conversion of clinical guidelines from free text, through semi-structured text, to a fully structured, executable representation. Thus, guidelines exist in a hybrid, multiple-format representation The three formats support increasingly sophisticated computational tasks. The tools perform semantic markup, classification, search, and browsing, and support computational modules that we are developing, for run-time application and retrospective quality assessment. We describe the DeGeL architecture and its collaborative-authoring authorization model, which is based on (1) multiple medical-specialty authoring groups, each including a group manager who controls group authorizations, and (2) a hierarchical authorization model based on the different functions involved in the hybrid guideline-specification process. We have implemented the core modules of the DeGeL architecture and demonstrated distributed markup and retrieval using the knowledge roles of two guidelines ontologies (Asbru and GEM). We are currently evaluating several of the DeGeL tools.

The digital library: an oxymoron?

"Virtual libraries" and "digital libraries" have become stock phrases of our times. But what do they really mean? While digital refers to a new form of document encoding and must be approached from that perspective, virtual resonates with aspects that modern philosophy treats with benign neglect at best. The word virtual harbors the notion of potential, and therein lies its hidden strength. Although strong commercial interests try to use the shift to a digital environment to redefine the political economy of knowledge, and thus virtualize libraries into a state of almost complete impotence, all hope is not lost. Librarians of virtualized libraries may well discover that they have re-empowered institutions if they place human interaction at the heart of their operations. In other words, rather than envisioning themselves as knowledge bankers sitting on treasure vaults of knowledge, they should see themselves as "hearts" dynamizing human communities. They should also see themselves as an essential part of these communities, and not as external repositories of knowledge. In this fashion, they will avoid the fate of becoming an oxymoron.

Clinical Digital Libraries Project: design approach and exploratory assessment of timely use in clinical environments.

OBJECTIVE: The paper describes and evaluates the use of Clinical Digital Libraries Project (CDLP) digital library collections in terms of their facilitation of timely clinical information seeking. DESIGN: A convenience sample of CDLP Web server log activity over a twelve-month period (7/2002 to 6/2003) was analyzed for evidence of timely information seeking after users were referred to digital library clinical topic pages from Web search engines. Sample searches were limited to those originating from medical schools (26% North American and 19% non-North American) and from hospitals or clinics (51% North American and 4% non-North American). MEASUREMENT: Timeliness was determined based on a calculation of the difference between the timestamps of the first and last Web server log "hit" during each search in the sample. The calculated differences were mapped into one of three ranges: less than one minute, one to three minutes, and three to five minutes. RESULTS: Of the 864 searches analyzed, 48% were less than 1 minute, 41% were 1 to 3 minutes, and 11% were 3 to 5 minutes. These results were further analyzed by environment (medical schools versus hospitals or clinics) and by geographic location (North America versus non-North American). Searches reflected a consistent pattern of less than 1 minute in these environments. Though the results were not consistent on a month-by-month basis over the entire time period, data for 8 of 12 months showed that searches shorter than 1 minute predominated and data for 1 month showed an equal number of less than 1 minute and 1 to 3 minute searches. CONCLUSIONS: The CDLP digital library collections provided timely access to high-quality Web clinical resources when used for information seeking in medical education and hospital or clinic environments from North American and non-North American locations and consistently provided access to the sought information within the documented two-minute standard. The limitations of the use of Web server data warrant an exploratory assessment. This research also suggests the need for further investigation in the area of timely digital library collection services to clinical environments.

The Virtual Hospital: experiences in creating and sustaining a digital library.

A university and its faculty encompass a wealth of content, which is often freely supplied to commercial publishers who profit from it. Emerging digital library technology holds promise for allowing the creation of digital libraries and digital presses that can allow faculty and universities to bypass commercial publishers, retain control of their content, and distribute it directly to users, allowing the university and faculty to better serve their constituencies. The purpose of this paper is to show how this can be done. A methodology for overcoming the technical, social, political, and economic barriers involved in creating, distributing and organizing a digital library was developed, implemented, and refined over seven years. Over the seven years, 120 textbooks and booklets were placed in the Virtual Hospital digital library, from 159 authors in twenty-nine departments and four colleges at The University of Iowa. The digital library received extensive use by individuals around the world. A new paradigm for academic publishing was created, involving a university and faculty owned peer reviewed digital press implemented using digital library technology. The concept has been embraced by The University of Iowa, and it has pledged to sustain the digital press in order to allow. The University of Iowa to fulfill its mission of creating, organizing, and disseminating information better.

Secure medical digital libraries.

In this paper, a secure medical digital library is presented. It is based on the CORBA specifications for distributed systems. The described approach relies on a three-tier architecture. Interaction between the medical digital library and its users is achieved through a Web server. The choice of employing Web technology for the dissemination of medical data has many advantages compared to older approaches, but also poses extra requirements that need to be fulfilled. Thus, special attention is paid to the distinguished nature of such medical data, whose integrity and confidentiality should be preserved at all costs. This is achieved through the employment of Trusted Third Parties (TTP) technology for the support of the required security services. Additionally, the proposed digital library employs smartcards for the management of the various security tokens that are used from the above services.

Bridging the gap between research and practice: The development of a digital library of research syntheses.

This article describes the development of a digital library as a resource for clinicians and researchers working with women with HIV infection. We wanted to find a new way of communicating the findings from the 114 studies that we used as the method case. The development of the SandBar Digital Library (http://sonweb.unc.edu/sandbar), a product of a 5-year project to develop the analytic techniques for qualitative metasynthesis, is described from its inception, including analyses of the potential users and how they might use such a resource. The Digital Library evolved over a 3-year period, with continuous feedback from a group of researchers and clinicians who are also experts in the care of HIV-positive people. It provides a concise and comprehensive compilation of findings in two major areas of concern for the seropositive women who were the participants in the studies: motherhood and stigma.

Information retrieval in digital libraries: bringing search to the net.

A digital library enables users to interact effectively with information distributed across a network. These network information systems support search and display of items from organized collections. In the historical evolution of digital libraries, the mechanisms for retrieval of scientific literature have been particularly important. Grand visions in 1960 led first to the development of text search, from bibliographic databases to full-text retrieval. Next, research prototypes catalyzed the rise of document search, from multimedia browsing across local-area networks to distributed search on the Internet. By 2010, the visions will be realized, with concept search enabling semantic retrieval across large collections.

Digital libraries--a quality concept.

The idea of digital libraries is not new, but recent developments have made the realisation of this idea more of a practical possibility than ever before. In particular, the availability of tools for easy access to information and for easy production of new information has encouraged traditional publishers to make their information available in digital networked form. but also made it possible for many individual authors to directly publish their own information on the Internet, bypassing traditional publishers and established bibliographic systems. Managing these new information resources is the task of Internet digital libraries such as OMNI. A key issue is the need to signpost the quality of information sources. A variety of ways of doing this are possible.

Creating and curating a pediatric radiology digital library to make the internet a useful reference tool for the radiologist.

BACKGROUND: To practice pediatric radiology optimally, radiologists need convenient access to organized and authoritative pediatric radiology information. The Internet has the potential for offering such convenient access, but the majority of information on it is poorly organized and of questionable authority. OBJECTIVE: The goal of this project was to create and curate a pediatric radiology digital library that will make the Internet a useful reference tool for the radiologist at the point-of-care. MATERIALS AND METHODS: A pediatric radiology digital library containing organized and authoritative pediatric radiology information from the Internet was created and has three components : (1) PediatricRadiology.com (http://pediatricradiology.com)--a catalog of pediatric radiology Web sites; (2) The MetaTextbook of Pediatric Radiology (http://www. vh.org/Providers/TeachingFiles/MetatextbookPedRad/MetaTBP edRad.html)--a catalog of pediatric radiology teaching file cases on the Internet; and (3) Paediapedia (http://www.vh. org/Providers/TeachingFiles/PAP/PAPHome.html)--an imaging encyclopedia of pediatric disease. The pediatric radiology digital library is curated regularly. RESULTS: Over 7 months, 223,689 pages of information were read and 26,972 images were viewed in the pediatric radiology digital library by 69,866 individual users, with 20% of the users from outside the United States. CONCLUSION: Creating a pediatric radiology digital library that identifies and organizes authoritative pediatric radiology information and makes it conveniently available can allow radiologists to use the Internet productively as a reference tool.

Electronic health record meets digital library: a new environment for achieving an old goal.

Linking the electronic health record to the digital library is a Web-era reformulation of the long-standing informatics goal of seamless integration of automated clinical data and relevant knowledge-based information to support informed decisions. The spread of the Internet, the development of the World Wide Web, and converging format standards for electronic health data and digital publications make effective linking increasingly feasible. Some existing systems link electronic health data and knowledge-based information in limited settings or limited ways. Yet many challenging informatics research problems remain to be solved before flexible and seamless linking becomes a reality and before systems become capable of delivering the specific piece of information needed at the time and place a decision must be made. Connecting the electronic health record to the digital library also requires positive resolution of important policy issues, including health data privacy, government encouragement of high-speed communications, electronic intellectual property rights, and standards for health data and for digital libraries. Both the research problems and the policy issues should be important priorities for the field of medical informatics.

Creating a pediatric digital library for pediatric health care providers and families: using literature and data to define common pediatric problems.

The goal of this study was to complete a literature-based needs assessment with regard to common pediatric problems encountered by pediatric health care providers (PHCPs) and families, and to develop a problem-based pediatric digital library to meet those needs. The needs assessment yielded 65 information sources. Common problems were identified and categorized, and the Internet was manually searched for authoritative Web sites. The created pediatric digital library (www.generalpediatrics.com) used a problem-based interface and was deployed in November 1999. From November 1999 to November 2000, the number of hyperlinks and authoritative Web sites increased 51.1 and 32.2 percent, respectively. Over the same time, visitors increased by 57.3 percent and overall usage increased by 255 percent. A pediatric digital library has been created that begins to bring order to general pediatric resources on the Internet. This pediatric digital library provides current, authoritative, easily accessed pediatric information whenever and wherever the PHCPs and families want assistance.
