This study aims to analyze the productivity patterns of authors in Nigeria using publications indexed in Medline from 2008 to 2012 based on Lotka’s Law. Lotka’s Law of scientific productivity provides a platform for studying inequality in authors’ productivity patterns in a given field and over a specified period.

This study covers all the journal articles on HIV/AIDS pandemic in Nigeria over a period of five years (2008-2012) in Medline, of which 512 articles were reported to have been published during this period. In this paper, 306 articles that had HIV/AIDS in the title, published in 20 journals, and articles that had HIV/AIDS as author keywords were analyzed. Because no local database that indexed biomedical literature from Nigeria was available, Medline was used, which is not only a robust and flexible database that includes articles from Nigeria but is also the largest medical database that indexes over six-and-a-half million articles from 3,400 biomedical journals.

While HIV/AIDS can be considered a global pandemic, Nigeria has the second highest number of new infections reported each year, and an estimated 3.7 per cent of the population is living with the dreaded disease. This study presents a general picture of the distribution of papers as single-author papers, multiple-author papers and the measures of co-authorship. The findings of the study reveal that in the productivity distribution for authors on the subject of HIV/AIDS, only co-authors and non-collaborative authors’ categories fit in the Lotka’s Law, whereas all-authors and first-author categories differ from the distribution of Lotka’s inverse square law.

The empirical evidence used in this paper was based on only articles of HIV/AIDS pandemic in Nigeria that had HIV/AIDS the title. Therefore, the findings of this study might not be the generalized to other biomedical research studies.

The originality of this paper lies in the fact that the productivity pattern of each of the different author categories on the subject of HIV/AIDS is a first of its kind in the Nigerian context.

This paper aims to understand job satisfaction as correlate with organizational change among personnel in computerized-based special libraries in Southwest, Nigeria.

The study used a survey approach in collecting data. The population of the study comprised all intermediate and senior personnel of the special libraries in Southwest, Nigeria involved in the study on grade levels 06 to 17. Based on the 180 response sample drawn, 148 responses were received from the survey.

The degree and level of satisfaction derived from one’s job is sine qua non to the level of productivity obtained in due cause. Job satisfaction varies from individual to individual and from place to place. Although, organizational change is the basis for spontaneous increase of job dissatisfaction. Findings of the study revealed that organizational change is seen as a precursor to influencing job satisfaction of employees but the level of job satisfaction of employees depend on the impact of organizational change.

It should be noted that a number of limitations exist relative to this research, the review of which should both place the research findings discussed, in an appropriate context and thereby suggest direction for future research. This study focused on employees attitudes in special libraries in six states of the federation at one time. Considering the fact that a very wide and varying cultural environmental differences which without doubt affected personnel dispositions in many different ways.

This paper differs from the previous literature in presenting statistical evidence to confirm the relationships between job satisfaction and organizational change and a range of potential outcomes.
