The Department of Education was one of the few departments that started with the establishment of the University of Maiduguri in 1976. Since then, it has grown in staff strength, student population and academic programmes. The Department of Education pioneered postgraduate education in the University of Maiduguri with the establishment of M.Ed. and PhD degree programmes and by the end of 1988/89 session; thus graduating one PhD and thirty M.Ed. candidates. The Department offers several PhD Programmes among which are: Educational
Administration and Planning, Educational Administration and Management, Curriculum and Instruction, Educational Psychology, Educational Measurement and Evaluation, Guidance and Counseling, Philosophy and Foundation of Education. Every Ph.D student must submit to the school of postgraduate studies, a thesis as part of the requirements for the award of Doctor of Philosophy of the University of Maiduguri. This thesis must have been orally defended before a panel of internal and external examiners. (Faculty of Education Prospectus, 2010).
Citation analysis according to Aina (2002) is a popular method in library and information science research in Africa, where references cited are statistically analysed in order to find out the common journals cited by researchers in a particular discipline. It is generally assumed to be part of bibliometric studies. Bibliometric study is usually applied to the quantitative analysis of publications in a particular discipline. Mathematical and statistical techniques are used to study the documents and to measure the patterns of publications. It is also used to measure the impact of publications through citation analysis. Bibliometric study also helps to find out the publication productivity, examine the authorship pattern for publications, identify the channels of communications used and ascertain the journal and language preference of an author. (Kousar and Mahmood, 2010.) Similarly, Bozimo (2006) stated that one of the librarian's primary tasks is to nourish the user's mind by providing information and, at the same time, observing the resources needed, requested and used. Perhaps no other type of study captures, in an unobtrusive manner, the resources used for teaching and research in universities than citation studies. Bozino (2006) further observed that, citations are references which researchers make because they consider that the cited paper have made some contribution to their thinking process in the course of writing a document. Accordingly, citations are "rewards" which individual writer accord to their colleagues whom they have personally assessed as having made some advancement to the store of information. Thus to be cited by a competent colleague is an honour truly deserved. While, for libraries, citation studies point to what documents should be acquired and also provide a peek into the way scholars seek information.
There are literatures on citation analysis in different disciplines and have been growing fast in the field of library and information science. Sam and Tackie (2007) observed that citations drawn from student's dissertations or term papers were sources of checklist used in numerous studies, the earliest being that of Emerson's analysis of twenty- three engineering doctoral dissertations at the Columbia University between 1950-1954 to determine the percentage of references held or not held by the other campus libraries in the University.
An earlier study by Iya (1996) on citation analysis of education dissertations at the University of Maiduguri, Nigeria revealed that out of the fifty-six (56) masters dissertations analysed majority of the postgraduate students used textbooks (40.3%) more than any other forms of library materials in writing their dissertations.
