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.
