An introductory presentation on the concept of Library Classification by Dr. Keshava, Professor, Department of Studies and Research in Library and Information Science, Tumkur University, Karnataka, INDIA.
This course is about the introduction to basic concepts, theories, principles, and standards of resource description, subject cataloging, and classification. This provides beginning level experience in organizing printed resources using the Resource Description and Access, including recording attributes of manifestation and item, identifying persons, families, and corporate bodies, and identifying works and expressions, construction of access points and authority data. Lastly, it deals about subject cataloging using the Sears List of Subject Headings and the assigning of classification numbers using the Dewey Decimal Classification Scheme.
Software is defined as a set of related computer programs (stored set of instructions) that governs the operation of computer system and makes the hardware run. The software for a computer system may be classified as system software (e.g. Operating System) and application software. System software is responsible for the overall management of the computer resources whereas application software is designed to perform certain tasks and thereby make computers able to perform different predefined jobs. Library automation software, as application software, performs day-to-day library activities through human interventions. Library automation packages are developed in view of the two most essential activities of any library – housekeeping and information retrieval.
The prime objective of any library is to meet the information requirements of its clients most effectively. To meet this objective, the library builds the collection in a planned manner and offers a variety of information services to inform the users what is available and whatever latest has been published in their areas of interest. All these services generate requests from the users for the original documents. The service that supplies the required document to the user on demand is known as Document Delivery Service.
Automating the library is a fruitful solution for avoiding majority of problems. But is also identified , that most of our libraries, especially school and public libraries, run their services with a very small budgetary/financial support. Such libraries may find it difficult to take initiative for automating the system. In such situations, chossing open source software is the best solution.
Today libraries are shifting their role from the traditional information resources to digital information resources, the libraries adopt new ways of information generation and dissemination because of the information technology and widespread utilization of the application of information and communication technology (ICT), increased computer networks and the evolution of the World Wide Web (WWW) enabled people to use the Internet for many reasons; for communication, for entertainment, for education, and so forth .
All types of libraries /information centres are organized to provide some basic services which are rendered either in anticipation or on demand from the users. The information services provided in anticipation are termed as alerting services as this alert the users about the new information of their interest. Broadly speaking the same is also termed as current awareness service . The primary aim of any library is to provide timely and quality services to its users
A MARC record is a Machine-Readable Cataloguing record. It is a format standard for the storage and exchange of bibliographic records and related information in machine. It is a standard for the description of the digital format of any item. This is a computerized method of recording the information for cataloguing purpose. These computer readable cataloguing records will help the computer programs to search for an display specified pieces of the information stored in a cataloguing record.
The development of online bibliographic databases and the rapid growth of online services accessible on the internet and world wide web (WWW) has made it possible to access information in ways not possible before. Libraries, whose primary mandate is to provide information, shifted the emphasis from collecting the information in hard copy to accessing information through electronic resources.
Many commercial online search systems permit the formation complex expressions by using Boolean logic to combine retrieval sets, Boolean logic is algebra of sets. In online information retrieval, Boolean logic is applied to sets of posting. Boolean logic (named after George Boole, a 19th century mathematician) defines logical relationships between terms in a search.
Library Automation refers to the use of computers to serve the needs of library users. The operations of a library get a quantum jump with the introductions of computers. The computers help to provide fast and reliable access to the resources available in the library as well as elsewhere. The application of computers in the library operations avoids repetitive jobs and saves lot of labour, time, speeds up operations, increases use of library resources. Computers are not only used as a tool for processing the data, but also for data storage and accessing. Planning for an automated system, no matter how big or small, should be part of an overall long-range plan for the library. Automation should always be used as a means to achieve overall better patron service.
Bibliographical information plays an important role information retrieval for the research community particularly in the field of science and technology. But during the bibliographical information exchange certain problems arise and more when the information interchange is on magnetic tape or CD-ROM. Different international organisations such as UNESCO/PGI, UNISIST, ICSU, IFLA, ISO have taken many steps towards the standardisation of bibliographic exchange formats. The process of standardisation follows a set of codes given by International Standard Organisation (ISO).
The main aim of any library is to provide access to proper information, to the right users in as possible as short time. In an environment of information explosion due to growing demands of the user and shrinking of financial resources, library is not able to obtain all the reading materials on demand. The only way to over come these problem is resources sharing through networking.
Library automation refers to the implementation of information and communications technologies (ICT) in the libraries and information centres for replacing manual library operations. The term automation is used for any process which is done through input and output operation. Library automation system includes maintenance of large bibliographical database. The status of library automation depends on Interaction between human and computer to accomplish various tasks of the library automation systems. In order to provide and also to enable the records in the database. The international standards for bibliographic description of library automation system uses sophisticated software tools and standard to index search and display information from the database created.
Hardware and Software requirements for Internet 2.pptxlisbala
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. The purpose of the internet is to communicate between computers that are interconnected with each other. Internet is accessible to every user all over the world.
The rapid development in an information technology has brought out a revolutionary change in the field of library system and services.The new information technology has changed the manual scenario of library to computerized automated library.
Evaluation of Library Automation software ppt.pptxlisbala
The selection of a good and perfect software package is not an easy job. A package which does not perform as expected or which requires expensive modifications will shake its creditability to the librarians to purchase them. A change of finding a right package could be improved by setting up an evaluation process based on common sense

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

means 'Book' and 'graphien' which means
'to write'. The original meaning of
'bibliography' was 'writing of books',
Nowadays bibliography means listing of
book/documents irrespective of the fact
that whether they are available in a
library or not.
3. Importanceof
Bibliography
Bibliography helps in :
@ literature selection work to be done
easily and efficiently;
@ knowing the literary output of a
particular country, in a particular
language and on a particular subject; and
@ promoting fruitful search by saving
the time of the researcher.
4. Bibliographic services
The Oxford English Dictionary defines" Bibliography, as
"A list of books of a particular author, Publisher or
country, or of those dealing with any particular theme; the
literature of a subject. In other words a bibliography is, " A
list of written, printed or otherwise produced records of
civilization., which may include books, serials, pictures,
maps, films, recordings, museum objects, manuscripts and
any other media of the communication
5. Aimsand
Functionsof
Bibliography
Verification of
Bibliographic
Detail:
Whenever we are to verify a title or collect
information on any subject we are to consult a
bibliography (subject bibliography). It also helps
us to ascertain bibliographical data about an
author thus helping in the identification of a
document.
Finding the
Existence:
A bibliography enables one to find out
what has already been written on his
subject and allows him to keep himself
well informed and up to date. This avoids
duplication in research, saving him both
time and money.
It is a Guide to
the Literature
of a Subject:
Bibliography is actually an index compiled
systematically on a subject, so it serves as a
guide to the literature of the subject.

A bibliography helps in locating the material or book in terms of place of publication,
location in the library on point of purchase.
Location of
Material:
A bibliography by adding a note to each document being listed, indicate the
value of the document to a given type of user. So it helps in books selection i.
e. which book should be consulted for a given purpose.
Book Selection:
Bibliography by listing of documents preserve all books, good, bad and
indifferent from oblivion.
It Preserves

7. Typesof
Bibliography
Analytical Bibliography: According to Roy B Stokes on
analytical bibliography involves “investigation of the
physical nature of the book which can be and frequently is
sufficiently exhaustive to enable all the circumstances of
the book manufacture and history to be revealed.
Descriptive Bibliography: Descriptive bibliography is the
application of analytical bibliography to the external form
of the book i.e. it concern itself with the materials forms of
books and not with their literary contexts.
Textual Bibliography: It is an application of analytical
bibliography to the contexts of books. It is a bibliography
applied to textual studies. The main purpose of such a
bibliography is to determine the effect of writing or the
printing process on the correctness or completeness of a
text.
8. Contd…
Historical Bibliography: The study of books “as
object of art” may be termed a historical bibliography.
It is concerned with art of writing, printing,
illumination and binding.
Systematic Bibliography: Systematic bibliography is
nothing but the listing of books and other reading
material according to some useful system of
reference scheme.
Primary Bibliography: Primary bibliographies are
those which are the original record of the whole or part
of their content.
General or Universal Bibliography: In general or
universal bibliography, it attempts to include books
published in every country and age and on all subject.
Incunabula Bibliography: This type of bibliography
lists the early printed Notes material up to 15th century.

Trade bibliographies: These types of bibliographies are brought
out by large publishing firms engaged in book production or
trade.
National bibliography: It is a comprehensive, almost complete
record of both written and printed output in a given country.
Secondary Bibliography: Secondary bibliographies are “those
in which material registered elsewhere is rearranged for the
convenience of research.
Subject Bibliography: A subject bibliography is a
comprehensive list of all books, periodicals articles, pamphlets
and other analytical materials that have appeared on that subject.

Author Bibliography: An author bibliography is
the list of writing by an author together with the
works on him by others.
Personal Bibliography: A personal bibliography
is a list of writings by others on the different
aspects of the life.
Bibliophilic Bibliography: A bibliography that
records old and rare books, first editions of
celebrated authors is known as bibliophilic
bibliography.
Selective Bibliography (Elective): This kind of
bibliography is concerned with the listing of only
selected and the best books
11. Needforbibliographicservices
The enormous growth of
recorded material on
print and non-print
media presents a
formidable problem in
their organizations and
control for effective use.
The bibliographic
organizations, thus, serve
as a pattern of effective
arrangement which
results from the
systematic listing of the
records of human
communication.
The rapid rise in the literature
both macro and micro has thus
necessitated and augmented the
use of various bibliographical
tools by the academic community
in their literary and scientific
pursuits. To organize the growing
recorded knowledge, the
librarians and documentalists have
developed various types of
bibliographical services for the
easy location and retrieval of the
material.
12. What is
bibliographic
services
Bibliographic services basically are those which
guide the users of the libraries to the documents
were in their required information is likely to be
available. Hence bibliographic services are those
information services of the libraries which
provide some are those information services of
the libraries which provide some bibliographic
description of the documents for which the users
are interested. So that information services like
CAS, SDI, Indexing and abstracting services of
the libraries.
13. Bibliographicservices
The comprehensive
term 'bibliographic
services' are included
bibliographies indexing
services,
abstracting
services,
documentation
lists, and
literature
search in
bibliographic
databases
both in
offline; and
online mode.
However, with the latest
developments and
advancements in the use of
computers and information
technology, the online search
services are being used
commonly for information
retrieval.
14. Bibliographical
Information
Services-OPAC
Preparing standard catalogue without much effort has become
possible due to Internet. The library professionals can also
access Internet resources for verification and downloading the
bibliographical information from other institutions. OPACs
via Internet have become a popular source of bibliographic
information. The librarians can provide the bibliographical
data through Internet access via OPACs of other libraries in
the world. The electronic documents can be supplied to the
users on demand through the network. Internet has also
affected the traditional classification system of our libraries.
Several libraries are opting the Cyber Dewey Decimal
Classification Summaries as a way to organize and navigate
resources onthe WWW. The Cyber Dewey website includes
alphabetical index to Dewey. The OPAC is a significant
service offered by libraries through their websites. It allows
users to search forthe bibliographic records contained within a
library's collections. Now days, some OPAC also provide
access to electronic resources and databases, in addition to the
traditional bibliographic records.
15. Indexing
Services
The word index is derived from the Latin word ‘indicate’ which
means to indicate or point out. ’ An index is a tool by means of
which a person who needs information has it indicated or pointed
out him. Allen Kent defined index "As a device that serves as a
pointer or indicator, most often alphabetic lists that include subjects
and name of people or places that are considered to be special
pertinence in a graphic records. Similarly, Geogre S. Bonn writes
that an index is a detailed alphabetical list of names, terms, topics,
places, formulae, numbers, or other significant terms in a completed
work with exact page reference to material discussed in that work/
Thus, an index is a systematically arranged list giving enough
information about each item to enable it to be a link between a
specific subject or topic and the identified document
16. Abstracting
Aervices
Abstract acts as retrieval media and current awareness tool.
According to Allen Kent "An abstract is a summary of a
publication or an article accompanied by an adequate
bibliographical description to enable the publication or article
to be traced. Robert L. Collinson writes that an abstract is the
"terse presentation in the author's own language, of all the
points made in the same order as in the original piece of
primary documentary information - that can be a book, a
research report, a periodical article, speech, the proceeding of
the conference, an interview, etc
In nutshell an Abstract is an abbreviated, accurate
representation of the basic characteristics of the original. In
many cases Abstracts function as surrogates for the original
document. Its purpose is to draw attention to the information
contained in the original document and provide whether or not
to refer to original. The Abstracts are frequently arranged in
classified order.
17. OnlineSearchServices
The concept of online searching was originally used to describe the process of directly
interrogating computer systems to satisfy particular requests for information . There are four
major components involved in online searching.
Information providers or database producers who make available the database(s) to be
accessed online.
A search service or host, which provides access to the database(s) and also provides software
for conducting the search.
Communication links, which connect the user/with the host and the database(s) and
A local workstation through which the user is linked to the service.
Online bibliographic services are responsible for mounting databases on a computer and
making the arrangements necessary for such databases to be searchable from a large number
of remote user workstations
18. Contd..
Online bibliographic services are responsible for mounting databases
on a computer and making the arrangements necessary for such
databases to be searchable from a large number of remote user
workstations. Online search services that provide access to a large
number of databases convert the databases into a uniform format with
some standardization in element names so that the basic commands
and search techniques apply across all the databases that are offered
by a given vendor.
19. Growthand
Developmentof
OnlineSearch
Service
The concept of online searching originated in the sixties, when the US
National Library of Medicine used computers in the production of the
printed 'Index Medicus' and the MEDLARS (Medical Literature
Analysis and Retrieval System) database was created. 1964 the library
began to offer batch searching of its MEDLARS system on demand,
and the following year the Lockheed Missiles Corp. system
developments Corp. (SDC) and the Chemical Abstracts Service began
their computerised search services. The first online dial-up service was
MEDLINE, the online version of MEDLARS, followed by commercial
Online Services from DIALOG (Lockheed) and ORBIT (SDC) in
1972. Since then many organizations have switched over to online
databases and search services. By 2002, there were as many as 750
public access databases from a range of different vendors. Initially, the
majority of online databases provided bibliographic references and thus
these were called bibliographic or reference databases. But over the
years, more and more databases are becoming available which retrieve
the content of documents rather than mere bibliographic references and
such databases are either full texts or databanks.
20. OnlineBibliographicServiceProviders
DIALOG : Dialog is the worldwide leader in providing
online-based information services to organizations seeking
competitive advantages in such fields as business, science,
engineering, finance and law
OCLC (Online Computer Library Centre, Ohio) :
OCLC offers an integrated suit of online, batch and
contract services and software to help ill building and
managing an electronic library based on the requirements,
budget and goals. The Online bibliographic service offered
by OCLC is the world's foremost bibliographic database
named World Cat. Since 1971, libraries have shared their
catalogs electronically to create the world's large database
of bibliographic information - World Cat (the OCLC online
Union Catalogue).

Retrieval Services provides comprehensive scientific
and technical aerospace information online. Users
including companies, research centres and universities
can take advantage of a broad range of online
information services from national centres
22. Literature
search
Online Dictionary of Library and
Information Science defines literature
search as follows: ‘Literature search is an
exhaustive search for published information
on a subject conducted systematically using
all bibliographic finding tools, aimed at
locating as much existing material on a
topic as possible, an important initial step in
any serious research
project’.(http://www.lu.com/odlis/)
23. Contd..
Literature search plays an important role in research
activities. Any researcher, while starting any new
research project needs to know in detail what has
already been published on her/his area of research.
Similarly, at the time of reporting the research
results, a researcher needs to review the literature to
compare the research results with other scholars
working in the similar field. This requires an
exhaustive search of previously published literature
on that subject and compilation of a bibliography.
Literature search is also carried out to solve any
research problem and to find out how other scholars
have handled the same problem.
24. Literature
searchthus
Helps in study and research;
Avoids duplication of research efforts;
Helps in solving research problem(s);
Assists in learning methods and approaches that
are appropriate for a particular field of study;
Helps to demonstrate that the researcher’s
contribution is new and different from others;
and
Assists in finding out new areas for research
25. Contd..
To satisfy information needs of researchers
(scientists, technologists, social scientists, etc.),
at times extensive literature searches are to be
carried out in several sources like books,
periodicals, non-book material, etc. Sometimes
to provide this service informal sources are also
consulted. Thus, the literature search in these
cases has to be more exhaustive, both in depth
and range. Besides bibliographies, other
secondary sources like abstracting and indexing
periodicals, reviewing periodicals are consulted
to find information.
26. Literature
searcheson
Demands
By some reasons users what to know
everything that has been published on a subject.
Need of such type of information can be
satisfied by undertaking a comprehensive
search in bibliographies and in indexing and
abstracting publications. It is known as
literature search service. Literature searching
can be done manually as well as by using a
computer. It can be done very fast using online
databases
27. Conclusion
An online bibliographic search service seeks to
mount a range of databases designed to meet the
needs of a specific users and act as an intermediary
between the database producer and the end-user.
These databases include both the producer and the
end-user. These databases include both the
bibliographic and document databases. There are a
number of factors that need to be considered in the
evaluation of online search services and the
database to which they provide access. The online
searches may be performed by intermediaries or
end-users.. An online search makes use of search of
index terms, and command languages and interfaces
