This study investigated the impact of library use on research productivity. The study was carried out using the survey research method. The population was made up of 359 postgraduate students at Babcock University, Ogun state. Sampling was enumerative as all members of the population were used for the study. A self designed questionnaire was used for data collection. Results showed that library services are of utmost importance to the research productivity of postgraduate students as all the respondents who were able to have at least one publication within the last two years affirmed using the library. However, printed books were ranked as the most important library service for research. Although personal assistance of library staff was ranked as the most important library service for research. Although personal assistance of library staff was ranked very low in importance, suggestions made by the respondent for the training of library staff in order to improve staff-user relationship show that the respondents value the assistance of library staff but may not be happy with the way library staff relate to users presently.
