It was concluded that that the academic librarians have certain level of reediness and the findings suggest that while there is some level of participation in resource sharing among academic librarians in federal polytechnic libraries in northern Nigeria, there are also need to increase their willingness for the activities. Among others, it was recommended that academic librarians explore and adopt other types of resource sharing activities, such as cooperative acquisition building and technology sharing.
