In recent times, advancement in technology has penetrated areas of library functions, especially, the establishment of an electronic library (e-library) system that has become commonplace in Nigeria. Studies have shown a low level of users" satisfaction with these resources. Thus, this study examined the influence of users" computer-self-efficacy and perception on users" satisfaction with e-libraries in Northern Nigerian universities. Descriptive survey research was adopted. A population of 7,028 users was considered out of which 1,406 was randomly sampled and used. A questionnaire was used to collect data. Hypotheses were tested with Spearman Rank-Order Correlation. Findings revealed that computer self-efficacy of users with e-libraries were high, even though their perceptions of e-libraries were low. There was a strong relationship between computer self-efficacy and satisfaction with e-library (r(951) = .164, p = .000), a positive correlation between perceptions and satisfaction with e-library (r(951) = .334, p = .000). It was therefore concluded that the satisfaction of users with e-libraries in the universities in Northern Nigeria would largely be influenced by their level of computer self-efficacy and perception. The study recommended the acquisition of relevant skills by the user for satisfactory utilization of the e-libraries. In particular, users should be assisted in identifying high-quality e-library resources.

Academic libraries are expected to provide information resources to meet the needs, expectations and aspirations of their users, and by extension, meet the teaching, learning and research objectives of the institutions. However, Nwirigi (2012) postulated that in recent time, technology has penetrated all areas of library functions and the establishment of an electronic library system has become commonplace in the 21 st Century. It has led to a dramatic switch to digital collections with an impact on library users and their perceptions of the library and its resources. The advent of technology in libraries has recreated the face of librarianship, which, according to Tenopir (2003) requires that the university libraries realign themselves with the new trend of service delivery. The emerging information trend has come along with networked systems, new methods of acquisition and utilization of information resources. It, therefore, means that university libraries have to create new ideas in service delivery that will bring about user satisfaction. Consequently, there are associated challenges of responding to these ever-increasing and changing digital information techn...
