DEFINITION OF INFORMATION 
SCIENCE 
 Information science is that discipline that investigates the 
properties and behavior of information, the forces governing 
the flow of information, and the means of processing 
information for optimum accessibility and usability. It primarily 
concerned with the analysis, collection, classification, 
manipulation, storage, retrieval, movement, dissemination, 
and protection of information.
DEFINITION OF INFORMATION 
SCIENCE 
This includes the investigation of information representations 
in both natural and artificial systems, the use of codes for 
efficient message transmission, and the study of information 
processing devices and techniques such as computers and 
their programming systems.
DEFINITION OF INFORMATION 
SCIENCE 
It is an interdisciplinary science derived from and related to such 
fields as mathematics, logic, linguistics, psychology, computer 
technology, operations research, the graphic arts, communications, 
library science, management, and other similar fields. It has both a 
pure science component, which inquiries into the subject without 
regard to its application, and an applied science component, which 
develops services and products." (Borko, 1968, p.3)
DEFINITION OF INFORMATION 
 The study of 
SCIENCE 
– the use of information, 
– its sources and development; 
– usually taken to refer to the role of scientific, industrial and 
specialized libraries and information units 
– in the handling and – dissemination of information. 
(Prytherch, 2005)
DEFINITION OF INFORMATION 
SCIENCE 
 The systematic study and analysis of the 
sources development 
collection, organization 
dissemination evaluation 
use, and 
management of information in all its forms, including the 
channels (formal and informal) and technology used in its 
communication. – –(Reitz, 2004)
DEFINITION OF LIBRARY 
SCIENCE 
 Library science as “a generic term for 
the study of libraries and information units, 
the role they play in society, 
their various component routines and processes, and their 
history and future development. (Prytherch,2005)
DEFINITION OF LIBRARY 
SCIENCE 
 Collection of reading material, its processing, organization 
and dissemination started with the advent of library. The 
knowledge and its implementation in respect of library may 
therefore be called library science 
 The study of principles and practices of library care, and 
organization and administration of a library, and of its 
technical, informational, and reference services. (Harrods 
‘Librarian’s Glossary)
DEFINITION OF LIBRARY 
SCIENCE 
 The professional knowledge and skill with which recorded 
information is 
selected, acquired, organized, stored, maintained, retrieved, and 
disseminated. 
To meet the needs of a specific clientele, usually taught at a 
professional library school qualified to grant the post-baccalaureate 
degree of M.L.S. or M.L.I.S. The term is used 
synonymously in the United States with librarianship 
(Reitz,2004)
BEGINNING OF INFORMATION 
 It is difficult to place an exact date to the beginning of information science. 
However, it is an old as man and civilization. When the Garden of Eden, the first 
man and woman, Hazrat Adam (a.s) and Hazrat Eve (a.s) were created by the 
Lord, and when commandment not to eat the fruit of the tree out of bounds, called 
the forbidden fruit, was violated. Adam and Eve, who were till then absolutely 
impervious to their genders, and other emotions were electrified, and first sin was 
committed. One may cite that great fact may be called the first and foremost 
information. 
(Encyclopedia of library and information science. New York: Marcel 
Dekker,1995.vol.56(19).p.137
PRIMARY HISTORY OF LIBRARY 
 From the pictographic, papyrus rolls, clay tablets and 
paper from information we have now moved to electronic era 
of 21st century.it is during 20th century that a lot work of 
library development has taken place. The clay tablet libraries, 
after covering a lot of distance, have now entered the age of 
electronic and virtual libraries. 
(Shera,Jesse H. Introduction to library 
science.Littleton,Col.:Libraries Unlimited,1976.pp.13)
PROGRESS OF L I BRARY SCI ENCE AS 
L I BRARY AND INFORMAT ION SCI ENCE 
 The first training program for librarians in the U.S. was established 
by Melvil Dewey in 1887. 
 It emerged as a separate field of study in the second half of the 19th 
century. 
 In the 20th century, library science was gradually subsumed under 
the more general field of information science. Today's graduate 
programs in library and information science are accredited by the 
American Library Association (founded 1876) and prepare students for 
professional positions in other areas of the information industry
PROGRESS OF L I BRARY SCI ENCE AS 
L I BRARY AND INFORMAT ION SCI ENCE 
 Later, the term Library Science was used in the title of S. R. 
Ranganathan's The Five Laws of Library Science, published in 1931, 
and in the title of Lee Pierce Butler's 1933 book, an introduction to 
library science (University of Chicago Press). Wikipedia 
 The earliest formal use of the term information science dates back 
to 1958 when the institute of information scientists (IIS) was formed 
in the United Kingdom. According to its founder, Jason Farradane, 
the use of the term information scientist,

RELATIONSHIP OF IS WITH LS 
The common ground between library science and information 
science, which is a strong one, is in the sharing of their social role 
and in their general concern with the problems of effective utilization 
of graphic records. 
Different library experts have mentioned the similarities between 
library science and information science in their own way. 
Here are their views
RELATIONSHIP OF IS WITH LS 
 Both fields emerged from the humanistic environment . 
(Curras, as cited in Nitecki, 1995.) 
 Both fields are in transition . (Nitecki, 1995). 
 Both study human behavior in information exchange 
aiming at the creation of knowledge and ideas .(Boyce, as 
cited in Nitecki, 1995). 
 Both approaches procure and handle information and 
apply new technology .(Bohnert as cited in nitecki,1995)
RELATIONSHIP OF IS WITH LS 
 Both shares the same problems in designing and operating 
information systems; 
 Both are service oriented and changing fast .(vaginos,as cited in 
Nitecki) 
 Information science is a part of library science, not a separate 
discipline; its claim to uniqueness has no empirical, philosophical, 
definitional or sociological evidence (Houster,as cited in nitecki,1995)
RELATIONSHIP OF IS WITH LS 
 Information work is an extension of library work 
(Ranganathan, as cited in A team of experts, 2005, 
p.4). 
 Librarianship always provided services and at present has 
merely modified them by adding new hardware. Hence there 
is a need to add word ‘information’ to the name of the domain 
‘librarianship’ (Stokes, as cited in nitecki 1995)
RELATIONSHIP OF IS WITH LS 
 Information science has both a pure science component, 
which inquiries into the subject without regard to its 
application, and an applied science component, which 
develops services and products. 
 Librarianship and documentation are applied aspects of 
information science (Borko-cited in Viswanathan, 2000, p.4) 
 Information science is offshoot of library science.
RELATIONSHIP OF IS WITH LS 
 Information science is sometimes the deinstitutionalized 
library science- the library without walls, where 
 the entire world of information is collection and 
 the librarian or information scientist is the agent/facilitator 
who acquires, organizes and disseminates that information 
(Rubin, 2000, pp.19-20).
RELATIONSHIP OF IS WITH LS 
 Traditional librarianship (manual systems) is library 
science while modern librarianship (ICTs-based, etc.) is 
information science (Fosdick, as cited in Chaudhry, 1992, 
p.95) 
 Library science is the foundation of information science 
except the development of computers (Rubin, 2000, p.20) 
 Concepts of information science are integrated with those 
of library science (Borko, as cited in Nitecki, 1995)
RELATIONSHIP OF IS WITH LS 
 Librarianship bridges the gap between information and its 
applications (Mathews-cited in Nitecki, 1995) 
 The social role of information science was formulated by its 
relations to librarianship & other fields (Saracevic-cited in Nitecki, 
1995) 
 Library science is concerned with the logistics and management 
of document. Information Science is concerned with the content of 
these documents and the work tasks of users including problem 
solving and decision-making
FIVE LAWS OF S.R. 
RANGANATHAN 
Five Laws of Library science Five laws on Information 
science 
Books are for use. Information is for use. 
Every reader his [or her] book. Every user his [or her] 
Information. 
Every book its reader. Every Byte of Information its 
user. 
Save the time of the reader. Save the time of Information 
user and staff. 
The library is a growing 
organism. 
Universe of Information is a 
growing organism. (Sen, B K, 
2008)

DIFFERENCE BETWEEN INFORMATION 
SCIENCE &L IBRARY SCIENCE 
 Both have same objectives but differ in techniques used. 
 Information science is independent of any particular 
environment, while, 
 library science depends on parental institution or community. 
 Information science is not institution-based while, 
 library science is institution/organization-based . 
(Gates, as cited in Nitecki, 1995).
DIFFERENCE BETWEEN INFORMATION 
SCIENCE &L IBRARY SCIENCE 
 The focus of information science is on the phenomenon of 
information. 
 Information science deals with the entire information 
cycle, from creation to use while 
 library science starts after the creation of information. 
(Rubin, 2000, pp.19-20),
DIFFERENCE BETWEEN INFORMATION 
SCIENCE &L IBRARY SCIENCE 
 Information science is an emerging field which is now a 
recognized discipline in an increasing number of major 
universities (Norton, 2000, p.25) 
 Information science is an inquiry, and library science a 
service (Wilson, as cited in Nitecki, 1995).
DIFFERENCE BETWEEN INFORMATION 
SCIENCE &L IBRARY SCIENCE 
 Information science investigates properties and behavior 
of information, its organization, storage, retrieval, 
interpretation, and utilization. 
 Library science concentrates on storing and disseminating 
knowledge contained in documents. (Borko, as cited in 
Nitecki, 1995).
CONCLUSION 
 Both librarianship and information science have the 
information perspective in common. 
 Library science and information science have very 
different histories, and, in particular, different methodological 
and values perspectives, they have in common this core 
relationship to the material of their work. (Bates, 1999)

  • 1. RELATIONSHIP OF INFORMATION SCIENCE WITH LIBRARY SCIENCE (702-theoretical Foundation of Information Science ) Presentation by Sadaf Batool M.Phil. (scholar )
  • 2. CONTENTS  Definition of information Science  Definition of Library Science  Beginning of Information Science  Primary history of library Science  Progress of Library Science as library and Information Science  IS &LS Concerned task
  • 3. CONTENTS  Relationship of IS with LS  Relationship of IS with LS according to S.R. Ranganathan’s five laws.  Difference between IS & LS  Conclusion  References
  • 4. DEFINITION OF INFORMATION SCIENCE  Information science is that discipline that investigates the properties and behavior of information, the forces governing the flow of information, and the means of processing information for optimum accessibility and usability. It primarily concerned with the analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and protection of information.
  • 5. DEFINITION OF INFORMATION SCIENCE This includes the investigation of information representations in both natural and artificial systems, the use of codes for efficient message transmission, and the study of information processing devices and techniques such as computers and their programming systems.
  • 6. DEFINITION OF INFORMATION SCIENCE It is an interdisciplinary science derived from and related to such fields as mathematics, logic, linguistics, psychology, computer technology, operations research, the graphic arts, communications, library science, management, and other similar fields. It has both a pure science component, which inquiries into the subject without regard to its application, and an applied science component, which develops services and products." (Borko, 1968, p.3)
  • 7. DEFINITION OF INFORMATION  The study of SCIENCE – the use of information, – its sources and development; – usually taken to refer to the role of scientific, industrial and specialized libraries and information units – in the handling and – dissemination of information. (Prytherch, 2005)
  • 8. DEFINITION OF INFORMATION SCIENCE  The systematic study and analysis of the sources development collection, organization dissemination evaluation use, and management of information in all its forms, including the channels (formal and informal) and technology used in its communication. – –(Reitz, 2004)
  • 9. DEFINITION OF LIBRARY SCIENCE  Library science as “a generic term for the study of libraries and information units, the role they play in society, their various component routines and processes, and their history and future development. (Prytherch,2005)
  • 10. DEFINITION OF LIBRARY SCIENCE  Collection of reading material, its processing, organization and dissemination started with the advent of library. The knowledge and its implementation in respect of library may therefore be called library science  The study of principles and practices of library care, and organization and administration of a library, and of its technical, informational, and reference services. (Harrods ‘Librarian’s Glossary)
  • 11. DEFINITION OF LIBRARY SCIENCE  The professional knowledge and skill with which recorded information is selected, acquired, organized, stored, maintained, retrieved, and disseminated. To meet the needs of a specific clientele, usually taught at a professional library school qualified to grant the post-baccalaureate degree of M.L.S. or M.L.I.S. The term is used synonymously in the United States with librarianship (Reitz,2004)
  • 12. BEGINNING OF INFORMATION  It is difficult to place an exact date to the beginning of information science. However, it is an old as man and civilization. When the Garden of Eden, the first man and woman, Hazrat Adam (a.s) and Hazrat Eve (a.s) were created by the Lord, and when commandment not to eat the fruit of the tree out of bounds, called the forbidden fruit, was violated. Adam and Eve, who were till then absolutely impervious to their genders, and other emotions were electrified, and first sin was committed. One may cite that great fact may be called the first and foremost information. (Encyclopedia of library and information science. New York: Marcel Dekker,1995.vol.56(19).p.137
  • 13. PRIMARY HISTORY OF LIBRARY  From the pictographic, papyrus rolls, clay tablets and paper from information we have now moved to electronic era of 21st century.it is during 20th century that a lot work of library development has taken place. The clay tablet libraries, after covering a lot of distance, have now entered the age of electronic and virtual libraries. (Shera,Jesse H. Introduction to library science.Littleton,Col.:Libraries Unlimited,1976.pp.13)
  • 14. PROGRESS OF L I BRARY SCI ENCE AS L I BRARY AND INFORMAT ION SCI ENCE  The first training program for librarians in the U.S. was established by Melvil Dewey in 1887.  It emerged as a separate field of study in the second half of the 19th century.  In the 20th century, library science was gradually subsumed under the more general field of information science. Today's graduate programs in library and information science are accredited by the American Library Association (founded 1876) and prepare students for professional positions in other areas of the information industry
  • 15. PROGRESS OF L I BRARY SCI ENCE AS L I BRARY AND INFORMAT ION SCI ENCE  Later, the term Library Science was used in the title of S. R. Ranganathan's The Five Laws of Library Science, published in 1931, and in the title of Lee Pierce Butler's 1933 book, an introduction to library science (University of Chicago Press). Wikipedia  The earliest formal use of the term information science dates back to 1958 when the institute of information scientists (IIS) was formed in the United Kingdom. According to its founder, Jason Farradane, the use of the term information scientist,

  • 17. RELATIONSHIP OF IS WITH LS The common ground between library science and information science, which is a strong one, is in the sharing of their social role and in their general concern with the problems of effective utilization of graphic records. Different library experts have mentioned the similarities between library science and information science in their own way. Here are their views
  • 18. RELATIONSHIP OF IS WITH LS  Both fields emerged from the humanistic environment . (Curras, as cited in Nitecki, 1995.)  Both fields are in transition . (Nitecki, 1995).  Both study human behavior in information exchange aiming at the creation of knowledge and ideas .(Boyce, as cited in Nitecki, 1995).  Both approaches procure and handle information and apply new technology .(Bohnert as cited in nitecki,1995)
  • 19. RELATIONSHIP OF IS WITH LS  Both shares the same problems in designing and operating information systems;  Both are service oriented and changing fast .(vaginos,as cited in Nitecki)  Information science is a part of library science, not a separate discipline; its claim to uniqueness has no empirical, philosophical, definitional or sociological evidence (Houster,as cited in nitecki,1995)
  • 20. RELATIONSHIP OF IS WITH LS  Information work is an extension of library work (Ranganathan, as cited in A team of experts, 2005, p.4).  Librarianship always provided services and at present has merely modified them by adding new hardware. Hence there is a need to add word ‘information’ to the name of the domain ‘librarianship’ (Stokes, as cited in nitecki 1995)
  • 21. RELATIONSHIP OF IS WITH LS  Information science has both a pure science component, which inquiries into the subject without regard to its application, and an applied science component, which develops services and products.  Librarianship and documentation are applied aspects of information science (Borko-cited in Viswanathan, 2000, p.4)  Information science is offshoot of library science.
  • 22. RELATIONSHIP OF IS WITH LS  Information science is sometimes the deinstitutionalized library science- the library without walls, where  the entire world of information is collection and  the librarian or information scientist is the agent/facilitator who acquires, organizes and disseminates that information (Rubin, 2000, pp.19-20).
  • 23. RELATIONSHIP OF IS WITH LS  Traditional librarianship (manual systems) is library science while modern librarianship (ICTs-based, etc.) is information science (Fosdick, as cited in Chaudhry, 1992, p.95)  Library science is the foundation of information science except the development of computers (Rubin, 2000, p.20)  Concepts of information science are integrated with those of library science (Borko, as cited in Nitecki, 1995)
  • 24. RELATIONSHIP OF IS WITH LS  Librarianship bridges the gap between information and its applications (Mathews-cited in Nitecki, 1995)  The social role of information science was formulated by its relations to librarianship & other fields (Saracevic-cited in Nitecki, 1995)  Library science is concerned with the logistics and management of document. Information Science is concerned with the content of these documents and the work tasks of users including problem solving and decision-making
  • 25. FIVE LAWS OF S.R. RANGANATHAN Five Laws of Library science Five laws on Information science Books are for use. Information is for use. Every reader his [or her] book. Every user his [or her] Information. Every book its reader. Every Byte of Information its user. Save the time of the reader. Save the time of Information user and staff. The library is a growing organism. Universe of Information is a growing organism. (Sen, B K, 2008)

  • 27. DIFFERENCE BETWEEN INFORMATION SCIENCE &L IBRARY SCIENCE  Both have same objectives but differ in techniques used.  Information science is independent of any particular environment, while,  library science depends on parental institution or community.  Information science is not institution-based while,  library science is institution/organization-based . (Gates, as cited in Nitecki, 1995).
  • 28. DIFFERENCE BETWEEN INFORMATION SCIENCE &L IBRARY SCIENCE  The focus of information science is on the phenomenon of information.  Information science deals with the entire information cycle, from creation to use while  library science starts after the creation of information. (Rubin, 2000, pp.19-20),
  • 29. DIFFERENCE BETWEEN INFORMATION SCIENCE &L IBRARY SCIENCE  Information science is an emerging field which is now a recognized discipline in an increasing number of major universities (Norton, 2000, p.25)  Information science is an inquiry, and library science a service (Wilson, as cited in Nitecki, 1995).
  • 30. DIFFERENCE BETWEEN INFORMATION SCIENCE &L IBRARY SCIENCE  Information science investigates properties and behavior of information, its organization, storage, retrieval, interpretation, and utilization.  Library science concentrates on storing and disseminating knowledge contained in documents. (Borko, as cited in Nitecki, 1995).
  • 31. CONCLUSION  Both librarianship and information science have the information perspective in common.  Library science and information science have very different histories, and, in particular, different methodological and values perspectives, they have in common this core relationship to the material of their work.
