This study examines the constructs of job satisfaction and organizational commitment. In this study, a canonical correlation analysis (CCA) was used to estimate relationships between identified dimensions of job satisfaction and organizational commitment. This study confirmed previous research showing that job satisfaction and organizational commitment constructs have positive and canonical relationship. The study samples are 405 of Library and Information Professionals selected randomly at the 2014 Annual General Meeting (AGM) of Nigeria Library Association held in Osogbo, Osun State, Nigeria. A structured questionnaire was prepared for the purpose of collection of data and the data were collected using Job Satisfaction Survey dimension of job satisfaction are autonomy, remuneration, promotion, supervision, condition of service, job significant, co-workers, skill variety, procedures as it is used by Humborstad and Perry (2011) while Organizational Commitment Scales affective, normative and continuance as it is used by Field (2002). In this study, three canonical correlation coefficients (CCC) were estimated, and the first two of them were significant (0.653 and 0.597, p0.001). Also the squared canonical correlation coefficient indicates the proportion of variance a dependent variable linearly shares with the independent variable generated from the observed variable’s set (i.e., the canonical variates) where job satisfaction accounted for 21.36% of the variance in organizational commitment while organizational commitment explained 17.15% of the variations in job satisfaction.
