Abstract

This study aims at chancing the information reclamation system is principally a system that stores records in a train for data applicable to each request. The purpose of similar system is to help access and use of knowledge which has been recorded. This study on information reclamation styles A case study of Onitsha divisional library is an disquisition into the colorful means espoused by the library under study in their information reclamation process. Particular attention is paid to being information reclamation styles use in the library and how suitable they are, the introductory advantages of digital information reclamation system over primer were also revealed by the study. The exploration methodology espoused for the exploration is the check system; data was collected using questionnaire together with observation. The study also revealed the information reclamation process in the library is homemade which the library organizes each accoutrements through cataloguing, bracket and indexing. Base on the problem encountered, some useful suggestions on how to ameliorate on the information reclamation function in the library were made. The study also concluded by suggesting that farther exploration study be made.

Background Of The Study

Information is a introductory mortal need. It’s demanded nearly in all angles of mortal bid similar as tutoring, literacy, business, decision timber, education, trip etc. No ultramodern society can serve effectively within the ferocious of information whether in print or non print format.

It’s thus material to know how these information can be harness, recaptured and circulated for use by the stoner or the society in a ultramodern world. The different styles of information reclamation are thus bandied in this write up with special interest on Onitsha divisional library.

The word information can not be mentioned in insulation of mortal beings. Information has been described as the master resource, the principal raw material and the principle product of ultramodern economics. Indeed before the ultramodern world, the ancient world has been dealing with information gathering storehouse and reclamation which were done in an ancient ways where papyrus, complexion tablets etc were used. Information can be seen as data that have been subordinated to some logical processing or functions able of answering a stoner’s query, be it recorded, epitomized or simply collected that would help in decision timber.

Information reclamation styles or systems came into beings as a means of icing that information generated and recorded don’t get lost over time. Before knowledge came, individualities formed the depository of knowledge. With libraries, depository of knowledge began to change into recorded form. currently the volume of new information being generated is similar that no existent can hope to manage with this information explosion and at the same time make them available to druggies. This led to the use of information reclamation with minimal cost in time, labour and plutocrat. Information reclamation system or system thus 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.

Reitz( 2004) defines information reclamation( IR) as the process, styles and procedure used to widely recall recorded information from a train of data. In libraries, quests is made generally for a know item or conformation on a specific subject, and the five is generally a mortal readable roster or indicator, or indicator, or a computer- grounded information storehouse and reclamation system, similar as an on- line canons and bibliography database. In the design of similar systems, a balance must be attained between speed, delicacy, cost and effectiveness. Any system that’s designed to grease the literature searching exertion may legitimately be called an information reclamation system. The roster, Index and bibliography, abstract as well as computers is known as information reclamation systems( IRS)

In the library moment, rather of the individual storing the knowledge in the brain and mind, we’ve the commercial store, the library, rather of the individual memory, we’ve the commercial memory. The library canons, bibliographies indicators and computers. These information recaptured systems( tools) contain the bibliographical details of documents similar as the author, edition, call- number, publisher, place of publication, date etc. These details help the stoner to identify the current title, author of the document without which reclamation becomes insolvable.

therefore, the experimenter purposes to probe the colorful process espoused by the public library under study in reacquiring for use known information particulars demanded to recoup documents on a particular subject problem and questions encountered.

A BRIEF HISTORY OF ONITSHA DIVISIONAL LIBRARY

In Nigeria, educational conditioning started with the appearance of the whitemen who introduced their religion to us. In the process, churches and seminaries were established. A forum was organized for the development of public libraries in Africa and it’s hold at the university council, Ibadan between 27th July and 21st August, 1953. This forum focuses on drawing up guidelines for the public library services. The forum also covered all aspects of public libraries and the major outgrowth includes the conformation of the professional library association also called West African library Association( WALA). The impact of WALA is relatively immense.

The Eastern Nigeria government also under the leadership of lateDr. Nnamdi Azikiwe too up the chance of UNESCO( United Nations Educational and scientific artistic association) conference and invites professionals from the regions to come and help to establish public library in the region. LateMr. Kalu Okorie come and surveyed the Eastern region and make recommendations, part of which is that there must be library legislation to give legal backing to the establishment of public library services. This recommendation is accepted by the indigenous government.

The Eastern part of Nigeria thus becomes the first region to have library board and library legislation. The establishment of the library actually takes effect in 1958 with the structure of the indigenous library headquarter at Enugu. This snappily followed with the establishment of divisional libraries at harborage Harcourt, Ikote Ekpne Umuahia and latterly at Onitsha and other branch libraries were also established Onitsha Divisional library was establish in 1967. It isn’t a separate library of its own. The library is use during the war as Onitsha high court until 1972, when the library is repaired and open for druggies discussion, following the creation of 19 countries in 1973 Anambra State is created out of the east central state just like Imo state, each of the countries had libraries within its area of governance.

On 11th September 1976, Anambra State Government Constitute the state library board with the responsibility of equipping other divisional libraries in the state. This board is set up to serve the people within their community. The accession of this library is substantially accoutrements from Enugu.

Onitsha divisional library is opened on the 28th November 1966, by the Military Governor, Chukwuemeka Odumegwu Ojukwu. The library has passed through numerous directors.

The present administration under the leadership ofMr. Peter Obi give Onitsha divisional library a new look as utmost of the old books has been weeded out and replace with further current bones , furnish it, repaint it, bedeck the emulsion, establish a Microsoft centre forE-library services. The Microsoft unit structure has been completed but outfit it’s still in progress(Mr. Peter Obi) bestowed reading divisions and shelves, tables and chairpersons for the Microsoft centre.

The former director of library is Barr. ChrisO. Onebunne who retired from service on April 2009 beforeMr. OsigweN. took over from him and come the present director of library services. The peremptory divisional library is Nkechi Udeze.

still, there re introductory problems which militates against the application of these styles or systems. Some of these problem includes Low knowledge position, Lack of finances, Government apathy to libraries, the pitiable conditions of our public libraries.
