The study investigated the use of contemporary media in library instruction and services in Federal University libraries in the South-South geopolitical zone of Nigeria. The study cut across six federal university libraries with a total population of 93 librarians. The findings revealed an adoption and use of contemporary media such as social media, text messages, and WhatsApp for library instruction and services. Some of the identified setbacks in the use of contemporary media for instruction and services in Federal University libraries in the South-South zone of Nigeria are inadequate Internet access, training, ICT skill, technophobia, and data. No adoption of contemporary media would affect patronage and adequate delivery of library instruction and services to library patrons who are dispersed in different geopolitical locations. The moderate use of email and scantily use of library Blog, library website, ask a Librarian, and FAQ, with a general no use of radio broadcasting and video conferencing revealed some backwardness. Therefore, the need for the library Management of Federal Universities in the South-South geopolitical zone of Nigeria to encourage librarians the use contemporary media for library instruction and services in university libraries as consistent usage would attract more users to use library resources.
