This study evaluated the effectiveness of communication in enhancement of library services at Delta State University, Abraka, Nigeria. An ex-post-facto descriptive research design was adopted. A questionnaire was used to collect data, and frequency distribution and percentages were used to analyze it. The findings revealed that effective communication enhanced library services. There was a contrary view on the use of oral communication. While library staff applauded the use of oral communication in library operations, most users said it does not encourage research. The low level of ICT usage was also observed. As a result of these findings, recommendations were made.
