The study’s goal is to look into librarians’ core competencies and information and communication technologies (ICT) skills as indicators of resource sharing services in federal university libraries in South-South Nigeria. Descriptive survey and expost-facto designs were used. Respondents were federal university librarians. Two hundred and sixty (260) copies of the questionnaire were distributed, but only two hundred and thirty-eight (238) were collected. Three study questions were answered using mean and standard deviation.

The findings revealed that librarians possess core competencies needed for library services. The study shows that librarians have advanced ICT skills, allowing them to share library resources and services. These university libraries are well-prepared to foster collaborative acquisition and sharing of information resources. It also shows that librarians are responding positively to technology changes, despite the fact that resource sharing appears to be outpacing them.

It was proposed that librarians have a positive approach to ICT adoption and that university administrators make efforts to invest in ICT infrastructures.
