Citation analysis is the study of the impact and quality of an article, an author, or an institution based on the number of times a scholarly work and/or author has been cited by others (Fordham University Libraries, 2018). It is the examination of the frequency, patterns, and graphs of citations in documents. It uses the pattern of citations, links from one document to another document, to reveal properties of the documents ("Citation analysis", n.d). Gohain and Saikia (2014) affirmed that it is useful for understanding subject relationships, authorship pattern, impact, publication trends, and bring out useful information like the relative use of different kinds of documents such as books, periodicals, e-resources, reports, projects, thesis, conferences, standards, and patents which can be better utilized for bibliometric studies in many respects. Bibliometric study or assessments of university research are now increasingly valued by research managers in higher institution as a form of strategic input to decision-making (Boshoff and Akanmu 2017).
The Department of Chemical and Petroleum Engineering is one of the four (4) different engineering departments established in College of Engineering of Afe Babalola University AdoEkiti (ABUAD), Nigeria in September 2010, when the university came into existence. It runs two (2) degree programmes; Petroleum Engineering and Chemical Engineering that are fully accredited by the Nigerian University Commission (NUC). Its purpose is to produce competent engineers who are of high standard in Petroleum Engineering and Chemical Engineering. This will be achieved through the familiarization of students with the basic theoretical and practical tools and techniques required for excellent performance in their future professional work. The programmes were also created to provide world class training, research, consultancy and extension services to the oil & gas, and allied industries.
Presently, the students' population has grown to one hundred and sixty five (165) in Petroleum Engineering and one hundred and eighteen (118) in Chemical Engineering degree programmes. Petroleum Engineering has eleven (11) lecturers, while Chemical Engineering has nine (09) lecturers. In addition to its programmes, the Departments commenced its Master degree in the two programmes in 2017. The programmes have led to the production of numerous project reports mandated to be submitted by undergraduate students at the end of their academic programmes in partial fulfillment of the requirements for the award of Bachelor of Engineering (B.Eng) Degree in Petroleum Engineering and Bachelor of Engineering (B.Eng) Degree in Chemical Engineering at Afe Babalola University. In preparing the project reports, the students consult various types of information materials available in university and/or engineering libraries as the case may be.
The engineering librarian in charge of these libraries has a crucial role to play in enhancing effective utilization of various research materials of their library knowing fully well that engineering is a field that is fast developing as a result of scientific and technological advancement. It is the responsibility of the engineering librarian to provide and guide engineering students on how to access information materials needed for their studies, research and other academic related programmes. That is the reason engineering librarian need to have adequate knowledge of the basic engineering services and the relevant components of the collection in order to be able to discharge his/her duties which are essential attributes of a given profession. In some instances, librarians often wonder what resources students use for research and whether the library provides access to these resources (Wilson, 2012). This is one of the reasons why librarians or libraries use citation analysis as measurable tools on their collection to ease these challenges.
The analysis of the citations of such projects submitted is in line with one of the major tasks of any university library in evaluating its impact in the area of usage and loans to users (Iivonen et al., 2009 in Maz-Machado, 2012). It will provide the real pictures of the citation made to information materials used by the graduating students. Edzan (2007) pointed out that librarians have been using citation analysis as a means to determine the usage of their collection development while others have used it to look at undergraduate information behaviour. It is against this background that this study examined the citation analysis of projects submitted to the Department of Chemistry and Petroleum Engineering of Afe Babalola University, Ado-Ekiti, Nigeria. Within this context, the researcher will be looking at the year the projects were submitted, source of citations, recency of the citations, types of authorship, as well as highest and lowest citation made by an individual project.
Objectives of the Study
The main objective is to evaluate the information materials use in the Department of Chemical and Petroleum Engineering of Afe Babalola University, Ado-Ekiti, Nigeria. The specific objectives are to:
> determine the project reports submitted per year by the graduating students;
> find out the average number of citation per projects;
> examine citation made according to the types of information materials;
> determine the recency of information materials cited;
> find out the types of authorship cited; and
> identify the highest and lowest citation by an individual projects
Citation analysis helps to evaluate and interpret citations received by articles, authors, institutions, and other indicators in order to identify the quality of the information sources which enable librarians in taking decision on user needs, users most used information resources and other varying information about the users (Curtis 2005 and Coleman 2005). Sam and Tackie (2007) quoting Smith indicated that it helps to determine what titles to purchase, to discontinue, or to weed. Librarians in various disciplines use it to guide against costly low used/ unused journals, purchase needed materials...
