1.1 INTRODUCTION
A good collection of books is the main activity of each library. In order to develop a good collection, documents of various types and in different physical forms are to be produced. Therefore, selection and acquisition of legal materials are two different functions/activities being carried out in order to improve the quantity and quality of materials available in the law library. Selection of materials involves deciding which materials are to be acquired for a library. Anieke (2004) quoting spiller (1991) opines that selection means “evaluating and choosing materials to add to the library stock” in other word, it involves deciding what books and non-book materials to be purchased. However, Eze and Eze (2006) in an attempt to differentiate selection from acquisition rightly observe that many persons assume that selection and acquisition work are one and the same process. They posite that even though they are related, that acquisition is the process by which the library physically secures (through bringing gifts or exchange) the items that selection personnel has identified as desirable additions to the collection.
Apparently, the law library belongs to the category of special libraries. And Nnadozie (2007:86) observed that the collection of the special library reflects the subject interest of the sponsoring organization. He further asserts that the selection policies of special libraries are careful worded to ensure that the books and publications relating to the research preoccupation of the parent body are acquired.
According to Oduagwu (2002:70) selection must precede acquisition. He explains that what to select depends on the type of library since each library is interested in serving primarily its clientele which could be homogenous or heterogeneous. The believed that selection as the most important function of the acquisition department should be performed in a systematic ways.
Anyanwu, Zandet and Amadi (2006), sees acquisition as the process of obtaining library materials to satisfy the needs of the users. To the acquisition work as a means by which book and non-book materials are added to the library. They further explain that selection of library materials is important because literature explosion publication of many library materials as no library can purchase all the materials needed.
Because the legal researcher usually need to have the most up-to date version of the law, as well as to be certain that an approved applicable case has not been overused by a higher court, or that a status has not been amended, repealed or found to be unconstitutional. Selections of legal materials or publications becomes a necessity and rely on variety of means for regular supplementation and up-dating.
In selecting and acquiring of legal materials problems like poor communication service, poor management of the library vote, poor quality of locally published book, inarticulate collection development policy. etc. are encounters acquisition of legal materials, both primary source materials such as court reports, volumes of statutes, journals etc. and secondary sources of materials needs to be effectively and efficiently selected by qualified law librarians before procurement takes place.
Historically, the law libraries are closely tied to the history of the judiciary system as well as to the history of the development of formal legal education. In the United States, the college of William and Mary lays claim to founding of the first professorship in law and the beginnings of a small collection of law books within the confines of the college library in 1779. The Harvard law library, now the largest law library in the United State, was established in 1817. Yet, until the primary focus for legal education moved in the late nineteenth century to the university from the law office, where aspiring lawyers and read the law under the tritelage of established practitioners, few law libraries (other than Harwards) compare in size and breadth of collection with Bar Association libraries of collection with rare developed to meet the needs of the practicing bar. However, the major concern in this piece of work is the problems of selection and acquisition of legal materials by law libraries in Nigeria with particular reference to Imo state Judiciary library (system) Owerri.

1.3 PURPOSE OF THE STUDY
The primary aim of the study is to fulfill the requirement of obtaining the ordinary National Diploma (OND) certificate. It is also the belief of the writers, that this work will be useful to researcher who may which to carry out further research in the area. Besides, it will serve as a reference source in law libraries where selection and acquisition are not properly carried out.

1.4 OBEJCTUVE OF THE STUDY
The specific objectives of the study are as follows:
 To find out the problems encountered in selection and acquisition of legal materials by law libraries in Nigeria.
 To ascertain if legal materials are selected and acquired in the library under study
 To find out the type of legal materials being acquired.
 To identify the channels of acquisition of legal materials
 To find out the criteria’s used in selection and acquisition of legal materials
 To ascertain those involved in selection of legal materials.

1.5 SIGNIFICANCE OF THE STUDY
The study will be of great value to researcher conducting their studies on selection and acquisition of legal materials in law libraries or on other closely related subjects.
The study therefore is meant to provide the right perception of the relevance of selection and acquisition of legal materials in law libraries as a unique function. Above all, the research will serve as a reference documents for both theoretical and applied study is selection and acquisition of library materials.

1.6 RESEARCH QUESTIONS
In other to achieve the specified objectives of the study the research formulated the following research questions to serve as a guide in adhering to the focus of the study.
 What are the problems facing selection and acquisition of legal materials by law libraries in Nigeria?
 Are legal materials selected and acquired in your library?
 What types of legal materials are being acquired by your library?

1.7 SCOPE OF THE STUDY
This research work is centred on “The problems of selection and acquisition of legal materials by law libraries in Nigeria with special emphasis to Imo state judiciary library. However, the limitation of the study is that of time and finance.
The time frame is not enough to allow for the generation of much data. Another is finance which is a major constraints as needed to travel often to be able to generate the facts needs to back up this study.
