INFORMATION RETRIEVAL SYSTEMS IN ACADEMIC
LIBRARIES (A CASE STUDY
OF FEDERAL POLYTECHNIC,
NEKEDE OWERRI)
ABSTRACT
Information
retrieval systems in libraries are basically systems that store record in a
file for data relevant to each request, retrieve the data and provide the
information on request. The purpose of such system is to help access and use of
the knowledge which has been recorded. This study on information retrieval
systems in libraries a case study of Federal Polytechnic Libraries, Nekede,
Owerri is an investigation into the various means adopted by the library under
study in their information retrieval process. Particular attention was paid to
the existing information retrieval systems in use in the library and how
suitable they are, the basic advantages of digital information retrieval over
manual were also revealed by the study. The research methodology adopted for
the research was the survey method, data was collected using questionnaire and
oral interview together with observation. The study also revealed the
information retrieval process in the library is manual which the library
organizes its materials through cataloguing, classification and indexing. Based
on the problems encountered, some useful recommendations on how to improve on
the information retrieval functions in the library were made. The study also
concluded by suggesting that further research study should be made.

CHAPTER ONE
INTRODUCTION
1.1
BACKGROUND
TO THE STUDY
Information
is a basic human need. It is needed in all facts of human endeavour. No society
and libraries can function effectively without the intensive of information
whether in print or non-print format.
It
is therefore pertinent to know how this information can be retrieved and
disseminated for use by the users or the society in a modern world. The
different systems of information retrieval in academic libraries are therefore
discussed in this write up with special interest on Federal Polytechnic Library
Nekede, Owerri.
The
world in information cannot be mentioned in isolation of human beings. Information
has been described as the master resource, the chief raw material and the
principle product on modern economic. Even before the modern world, the ancient
world has been dealing with information gathering, storage and retrieval which
were done in an ancient way where papyrus, clay tablets e.t.c. were used.
Information
can be seen as data that have be subjected to functions capable of answering a
users query, be it recorded, summarized or simple collection that would help in
decision making, according to Uwem, (2008) defined information as a finished
product ready for use, the source and medium of communication not with sanding
information therefore, can help to ensure the effective use of other resources
when it gets to the right people and at the right time.
Consequently,
the basic objective of any library be it academic, public, school or special
library includes the acquisition of information, surveying materials properly
processing, organizing, storing and retrieving for disseminating such information
to interested users. Hence every academic libraries whether the limits of its
fund, develop sufficient information both in scope, nature and size to support
the users information needs and aspiration will largely depend on a specific
question and its ability to supply known information are produced in form of
language even to retrieve information is inform of language, most times, the
users found it increasingly difficult to cope with the basic problems of
accessing particular information items for use.
This
research purpose to investigate the various system adopted by the academic
library under study in retrieving for use known information items when needed
and to retrieve documents on a particular subject problem and questions
encountered.
1.2
STATEMENT
OF THE PROBLEM
The
period under review in this research work is of great importance in academic
libraries. It is a period of technological information explosion.
This
is a period when many retrieval systems exists, where more efficient and
accurate retrieval system has been developed like computer and internet which
links different but many stations together.
However,
there are basic problems which militate against the efficient utilization of
these resources and these problems include.
a. Lack
of funds
b. Government
apathy to academic libraries
c.
Low literacy level in
Nigeria
d. Poor
computer informed staff in the academic libraries.
1.3
Objective of the study
In
order to evaluate information retrieval system in Federal Polytechnic Library
Nekede, Owerri, the following objectives are to be focused.
i.
To identify the
existence of information retrieval system in the library.
ii.
To know how
information resources are organized in the library in its retrieval effort.
iii.
To identify the
problems encountered by the library in its information retrieval effort.
iv.
Identify the process
on how information retrieval system are improved in the library.
v.
To highlighting the
changes of information retrieval system in the library.
1.4
SCOPE OF THE STUDY
This
study is limited to the information retrieval processes in academic libraries.
This study is further narrowed down to academic libraries and specific focus on
Federal Polytechnic Library Nekede. The different information retrieval
processes were reviewed with unique interest in the libraries as it applies to
the library under study. This library was chosen so as to evaluate the
developments and the changes that have taken place in the library under study
as regards to information retrieval system.
1.5
SIGNIFICANCE
OF THE STUDY
This
study is significant because there is no society that can function without
information. So information can only be relevant when it gets to the right
people at the right time and in the right dosage. It is sine-qua-non to library
users, librarians, administration and the entire society.

DEFINITION
OF TERMS
For
the purpose of understanding this project work under study, the following items
are relevant to point out. They are as follows: -
ACADEMIC LIBRARY:
An academic library is a library that is been established in higher
institutions, such as universities, polytechnics and college of education which
serve the teaching and research needs of students and staff. This library serve two complementary purpose
which are to support the school’s curriculum and to support the research or the
university faculties and students.
INFORMATION:
This refers to a fact told or communicated that, fact is a piece of information
that is referred as true. It can also be seen as a processed data which is
communicated or receive which also can be used in making an information
decision.
INFORMATION RETRIEVAL:
This means the systematic storage and recovery of data as from a file and
catalogue or memory bank of a computer. It equally means document delivery such
as mails, photocopied document, data bank mail, links, library searches, personal
files, catalogue and database design.
INFORMATION STORAGE
AND RETRIEVAL SYSTEM: This refers to a
system that stores record in a file, accept requests for information, search
the file for data relevant to each request, retrieve the data and provide the information
to the requester. The aim of such system is to help access and use knowledge
that has been recorded. An effective information system stores a large number
of records yet retrieves desired record rapidly and accurately in response to
requests.
