Definition and Purposes of a Digital Library

Association of Research Libraries

October 23, 1995

Definition

There are many definitions of a “digital library.” Terms such as

“electronic library” and “virtual library” are often used synonymously. The

elements that have been identified as common to these definitions[1] are:

* The digital library is not a single entity;

* The digital library requires technology to link the resources of many

* The linkages between the many digital libraries and information

services are transparent to the end users;

* Universal access to digital libraries and information services is a

goal;

* Digital library collections are not limited to document surrogates:

they extend to digital artifacts that cannot be represented or

distributed in printed formats.

Purposes

The purposes of a North American digital library system[2] are:

* to expedite the systematic development of: the means to collect,

store, and organize information and knowledge in digital form; and of

digital library collections in North America ;

* to promote the economical and efficient delivery of information to all

sectors of North American society;

* to encourage co-operative efforts which leverage the considerable

investment in North American research resources, computing and

communications network;

* to strengthen communication and collaboration between and among the

research, business, government, and educational communities;

* to take an international leadership role in the generation and

dissemination of knowledge in areas of strategic importance to North

America ;

* to contribute to the lifelong learning opportunities of all North

Americans.

2. UCLA-NSF Workshop on Social Aspects of Digital Libraries, Final report, November, 1996 http://www-lis.gseis.ucla.edu/DL/UCLA_DL_Report.html#introduction

The core premise of the workshop was that digital libraries represent a set of significant social problems that require human and technological resources to solve. Workshop participants were charged with appraising the scope of social aspects of digital libraries, assessing what is known about these problems, and identifying the research and development issues that need to be addressed to solve them. Our first task was to define “digital libraries.” We determined that digital libraries encompass two complementary ideas:

• Digital libraries are a set of electronic resources and associated technical capabilities for creating, searching, and using information. In this sense they are an extension and enhancement of information storage and retrieval systems that manipulate digital data in any medium (text, images, sounds; static or dynamic images) and exist in distributed networks. The content of digital libraries includes data, metadata that describe various aspects of the data (e.g., representation, creator, owner, reproduction rights), and metadata that consist of links or relationships to other data or metadata, whether internal or external to the digital library.
• Digital libraries are constructed — collected and organized — by a community of users, and their functional capabilities support the information needs and uses of that community. They are a component of communities in which individuals and groups interact with each other, using data, information, and knowledge resources and systems. In this sense they are an extension, enhancement, and integration of a variety of information institutions as physical places where resources are selected, collected, organized, preserved, and accessed in support of a user community. These information institutions include, among others, libraries, museums, archives, and schools, but digital libraries also extend and serve other community settings, including classrooms, offices, laboratories, homes, and public spaces.

The first idea emphasizes the fact that digital libraries are computer-based systems constructed for people to use and that they are extensions of information storage and retrieval systems. The second emphasizes the belief that digital libraries should be constructed in a way that accommodates the actual tasks and activities that people engage in when they create, seek, and use information resources; in this sense they are an extension of physical environments. Both assert that digital libraries are sets of information resources collected and organized on behalf of a community.

Embedded in this definition are complex concepts with meanings that vary by context and by field of study. The terms ìinformation,î ìcommunity,î and ìlibraryî are the most problematic. Definitions of ìinformationî abound: signal processing; sensory perception; data generated by individuals and groups; objects that can be managed in retrieval systems; intellectual commodities that can be exchanged in the marketplace; etc. ìCommunityî implies a group of people with something in common, but those common features may be permanent or temporary, static or dynamic, innate or selected; biological or cultural, etc. — and any one individual can be a member of many communities at once. A ìlibraryî is often narrowly defined in technical contexts as a database application, while in other contexts a ìlibraryî is a social institution that selects, collects, organizes, preserves, conserves, and provides access to information on behalf of a community. Even the term ìdigitalî is problematic, for it reflects both ìdigital objectsî — those created in digital form, and “digitized objects” — those that are representations (e.g., scanned images, keyed text) of objects in other forms.

As a National Challenge Project under the NII/IITA, Digital Libraries represent a set of significant societal problems that require human and technological resources to solve.

Digital libraries represent two complementary ideas:

• Digital libraries are a set of resources and associated technical capabilities for creating, searching, and utilizing information. In this sense they are an extension of information storage and retrieval systems that manipulate digitized data in any medium (text, images, sounds; static or dynamic images) and exist in distributed networks.
• Digital libraries are virtual communities in which individuals and groups interact with data, information, and knowledge resources and systems. In this sense they are an extension, enhancement and integration of a variety of information institutions as physical places where resources are selected, collected, organized, preserved, and accessed in support of a user community. These information institutions include, among others:

• Libraries
• Museums
• Archives
• Schools
• Laboratories

4. Gladney, Henry M. et. al. Digital Library: Gross Structure and Requirements (Report from a Workshop.) IBM Research Report RJ 9840, May 1994. http://www.ifla.org/documents/libraries/net/rj9840.pdf

A digital library is a machine readable representation of materials which might

be found in a university library together with organizing information intended

to help users find specific information. A digital library service is an assemblage

of digital computing, storage, and communications machinery together with the

software needed to reproduce, emulate, and extend the services provided by

conventional libraries based on paper and other material means of collecting,

storing, cataloging, finding, and disseminating informatio n. A full service digital

library must accomplish all essential services of traditional libraries and also

exploit digital storage, searching, and communication.

Public, private, professional, school, commercial, and other kinds of library

emphasize different services, different kinds of information, and different service

styles. While any digital library instance may thus offer only partial services, the

technology suite from which library instances are assembled must permit

assembly of a full service library. In addition, this suite must shield the user

who wishes to draw on multiple libraries from inter-library differences which are

irrelevant to him.

What distinguishes a conventional library from a heap of things to read is

organization provided by someone other than the authors of the collected

materials. For a small, private collection this could be shelf organization; for a

large collection it is typically a descriptive catalog 2 which is distinct from the

collection, with at least one catalog record associated with each item held.

Not every database is a library, but every library is a database 3 . What distin-guishes

a library from an arbitrary database are certain data integrity and

security rules that constitute an implicit contract between custodians and users.

5. The NSF/ARPA/NASA Digital Library Initiative, FY 1994 Na93 states:

“Information sources accessed via the Internet are ingredients of a digital library. Today, the

network connects some information sources that are a mixture of publicly available (with

or without charge) information and private information shared by collaborators. They

include reference volumes, books, journals, newspapers, national phone directories, sound

and voice recordings, images, video clips, scientific data (raw data streams from instruments

and processed information), and private information services such as stock market reports

and private newsletters. These information sources, when connected electronically through

a network, represent important components of an emerging, universally accessible, digital

library.”

6. In a prior DL workshop report Fo93,p.65 , we find:

“A digital library is a distributed technology environment which dramatically reduces barriers

to the creation, dissemination, manipulation, storage, integration, and reuse of information

by individuals and groups.”

http://ei.cs.vt.edu/~dlib/def.htm E.A. Fox (ed.), Source Book on Digital Libraries, TR93-35, Dept. of Computer Science , Virginia Tech, (1993);

“Digital libraries are complex data/information/knowlege (hereafter information) systems that

help: satisfy the information needs of users (societies), provide information services (scenarios),

organize information in usable ways (structures), manage the location of information (spaces), and

communicate information with users and their agents (streams).”

(Edward A. Fox, July 1999, according to 5S Framework)

“Digital library work occurs in the context of a complex design space shaped by four dimensions:

community, technology, services and content”

integration”, pp. 219-225, guest editors' introduction to “Progress Toward Digital Libraries”, eds.

l

“The field of digital libraries deals with augmenting human civilization through the application of

digital technology to the information problems addressed by institutions such as libraries, archives,

museums, schools, publishers and other information agencies. Work on digital libraries focuses on

integrating services and better serving human needs, through holistic treatment irrespective of

interface, location, time, language and system. Although substantial collections may be created

solely for the use of individuals, we consider sharable resources one of the defining characteristics

of libraries. Libraries connect people and information; digital libraries amplify and augment these

connections.”

integration”, Information Processing & Management, 35(3):219-225, May 1999.)

“systems providing a community of users with coherent access to a large, organized repository of

information and knowledge. This organization of information is characterized by the absence of

prior detailed knowledge of the uses of the information. The ability of the user to access,

reorganize, and utilize this repository is enriched by the capabilities of digital technology”

l

“Digital library is a concept that has different meanings in different communities. To the

engineering and computer science community, digital library is a metaphor for the new kinds of

distributed data base services that manage unstructured multimedia data. To the political and

business communities, the term represents a new marketplace for the world's information resources

and services. To futurist communities, digital libraries represent the manifestation of Wells' World

Brain. The perspective taken here is rooted in an information science tradition.”

“an organized data base of digital information objects in varying formats maintained to provide

unmediated ease of access to a user community, with these further characteristics:

data base and removes them according to a coherent and accessible collections policy.”

“A library that has been extended and enhanced by the application of digital technology. Important

aspects of the digital library that may be extended and enhanced include :

– Collections of the library

– Organization and management of the collections

– Access of the library items and the processing

of the information contained in the items

– Communication of information about the items “

“The literature on digital libraries contains numerous, often dissimilar, definitions of 慸 igital library'. These definitions range from the digital library as a computer data repository or a collection of digital objects, to much broader definitions that consider the digital library to be an extension of the traditional library: that is, a library that carries out the traditional library functions of collection, preservation and access provision, while integrating, to an increasing degree, digital media and remotely accessible digital library services. For librarians, this last definition is most realistic….Digital libraries are libraries , with the same purposes, functions and goals as traditional libraries.” 1

…digital libraries provide for collection development, organisation, access, annotation and preservation, and deal both with information in digital form as well as digital management of information residing on physical media. My definition places additional emphasis on the need to consider users and usage as part of any analytical framework used to study digital libraries.
