However, many librarians in Nigerian academic libraries are still not taking full advantage of social media in personal and professional activities. This study examined the influence of computer self-efficacy and computer playfulness on social media use by librarians in private university libraries southwest, Nigeria. Descriptive survey research design was adopted for the study. A structured questionnaire was adopted as the instrument for data collection. The instrument was tested for reliability and the result showed a Cronbach Alpha value of 0.78. The study population consist of 127 librarians from sixteen academic libraries across southwest Nigeria. The entire population was included in the study due to the small size of the population. The quantitative data collected was analysed using both descriptive and inferential statistics. The study found that both computer self-efficacy (Adj. R2 = 0.604, p<0.05) and computer playfulness (Adj. R2 = 0.614, p<0.05) individually have significant influence on the use of social media among the respondents. Multiple regression analysis also revealed a significant combined influence of both variables on the use of social media among the respondent. The study concluded that the use of social by librarians remains the a good strategy to enhance library and information services in academic libraries. It was therefore recommended that continuous personnel development should be an integral part of the library programmes as a way to develop computer self-efficacy for librarians.
