This study examined the relationship between ICT competence of librarians and their job performance in the libraries of Michael Okpara University of Agriculture, Umudike and Abia State University, Uturu. Three research questions were answered and three hypotheses tested at 0.05 level of significance. The study adopted simple linear correlation design involving Pearson Product Moment Correlation. The population of the study was 136 librarians working in the libraries. The instrument used for data collection was rating scale titled librarians Information and Communication Technology Competency and Job Performance (LICTCJP). The research questions were answered using Pearson Product Moment Correlation (PPMC), while the hypotheses were tested using t-test of the significance of Pearson r. The findings of the study revealed that there is a very high and significant relationship between ICT competence of librarians and; cataloguing and classification of information; Selective Dissemination of Information (SDI) but there is a low but significant relationship between ICT competence of librarians and reference services provided in the libraries. Based on these findings the researchers recommend that ICT competence should be a major criteria for the employment of librarians in various libraries; the university administrations should provide on-the-job ICT training to the librarians in the various libraries; and the librarians should be monitored to ensure that the services provided in the libraries are done using ICT in order to meet up with international standards
