The study investigated the utilization of social networks for enhanced collaborative learning among library and information science students of federal universities in Southeast Nigeria. A descriptive survey was adopted for the study. The study adopted a multi-stage sampling technique. First is the purposive sampling technique. This enabled the researcher to sample the universities that were used for the research. The second is the proportionate stratified technique method to ensure greater representativeness of the sample relative to the population. Three federal universities offering library and information science in Southeast Nigeria were purposively sampled and 348 was the sample size. Six research questions were formulated in line with the purpose of the study. A questionnaire was used in the collection of data from 348 respondents, out of which 339 was properly filled and returned. Data obtained from the study were analyzed using mean and simple percentages and this formed the basis of the detailed analysis, recommendations and conclusions. The findings revealed that social networks like Facebook, WhatsApp, LinkedIn, etc are required for collaborative learning. The study also revealed that there is a high extent of utilization of social networks for collaborative learning practices and that social network contributes immensely to collaborative learning practice. The study recommended that, since social networks are becoming a trending learning environment and more common in interaction among students, educators and academic authorities should be intentional in designing the tasks involved in making it a tool for collaborative learning among undergraduate students.
