Review of Literature
Sasikala and Raju (2008) in their paper entitled 'Information use pattern in Economics' analyzed 24,699 citations from 192 doctoral theses awarded by Andhra University during 1950-2002. The findings of their study revealed that majority of the citations were from books (38%), followed by journals (35%). The subject distribution of doctoral theses revealed that more than half of the theses submitted were on 'Industrial Economics', followed by 'Labor Economics'. Their study also found that works of single authorship were predominant and half-life of literature in Economics was found to be 14 1/2 years. Burman and Sheela (2011) in their paper entitled 'Citation analysis of dissertations of Law submitted to University of Delhi' analyzed 3,052 citations from 33 LL.M (Master of Law) dissertations and found that 25.52% citations were from journal articles, followed by 22.21% citations from books. They observed that single authorship was more predominant (79.84%) in comparison to multiple authors. Majority of the cited journals were published from USA (41%), followed by India (37.41%) and UK (12.23%). 69.78% periodicals cited were from the field of Law, followed by Science and Technology (10.79%), Social Sciences (9.35%), Economics (7.9%) and Education (2.15%). 31.45% papers were cited within five years of their publication and half-life of periodicals in the field of Law was found to be 11 years. Trayambakrao and Sonwane (2012) in their paper entitled 'Citation analysis of Ph.D. theses on Economics submitted to Dr. Babasaheb Ambedkar Marathwada University' analysed that most cited documents were books (57.86%) and remaining 42.14% citations were from reports, journals, government publications, theses and others. The chronological distribution of citations shows that maximum number of citations (33.97%) was to publications published during 1999-2008. The authorship pattern of citations indicates that the single author citations were more in number (72.81%) than others. The language wise distribution of citations show that 1505 documents (52.33%) cited were in English language. The geographical distribution shows that Indian literature was mostly cited by the researchers (68.57%). The ranking of web citations show that only 26 citations (0.90%) were web citations and remaining 2850 citations (99.10%) were print citations. Hence, their study revealed that the printed resources were mostly preferred by the researchers than the web-citations.
Statement of the Problem
Citation analyses helps in formulating the need-based collection building policy and also help to provide authentic data to inform the librarians, information Manager, Information Officers, Documentation officer to make thoughtful decisions in the documents' selection. It helps the Librarians in evaluating the existing library collection and help to take decision which collection, specially the journals, is to be kept or discarded from the library and eventually helps in making decisions for the collection development policy. In view of the above, the present study was designed to investigate the citation analysis of Doctoral dissertation submitted in the field of Economics, at Panjab University, Chandigarh in order to find out the ranking of the cited journals, half life of journals and books, authorship pattern, their geographical and chronological distribution, etc. It will help the librarians to budget their resources depending on the usage of their collection.
