ABSTRACT

This study aims at finding the information retrieval system is basically a system that stores records in a file for data relevant to each request. The purpose of such system is to help access and use of knowledge which has been recorded. This study on information retrieval methods: A case study of Onitsha divisional library is an investigation into the various means adopted by the library under study in their information retrieval process. Particular attention is paid to existing information retrieval methods use in the library and how suitable they are, the basic advantages of digital information retrieval system over manual were also revealed by the study. The research methodology adopted for the research is the survey method; data was collected using questionnaire together with observation. The study also revealed the information retrieval process in the library is manual which the library organizes each materials through cataloguing, classification and indexing. Base on the problem encountered, some useful suggestions on how to improve on the information retrieval function in the library were made. The study also concluded by suggesting that further research study be made.

CHAPTER ONE

INTRODUCTION

1.1     BACKGROUND OF THE STUDY

        Information is a basic human need. It is needed virtually in all facets of human endavour such as teaching, learning, business, decision making, education, travel etc. No modern society can function effectively within the intensive of information whether in print or non print format.

        It is therefore pertinent to know how these information can be harness, retrieved and disseminated for use by the user or the society in a modern world. The different methods of information retrieval are therefore discussed in this write up with special interest on Onitsha divisional library.

        The word 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 of modern economics. Even before the modern world, the ancient world has been dealing with information gathering storage and retrieval which were done in an ancient ways where papyrus, clay tablets etc were used. Information can be seen as data that have been subjected to some logical processing or functions capable of answering a user’s query, be it recorded, summarized or simply collected that would help in decision making.

        Information retrieval methods or systems came into beings as a means of ensuring that information generated and recorded do not get lost over time. Before knowledge became, individuals formed the repository of knowledge. With libraries, repository of knowledge began to change into recorded form. Nowadays the quantity of new information being generated is such that no individual can hope to cope with this information explosion and at the same time make them available to users. This led to the use of information retrieval with minimum cost in time, labour and money. Information retrieval method or system therefore is the process of searching some collections of documents in order to identify those documents in order to identify those documents which deals with a particular subject.
