The study investigated importance of competitive intelligence approach in achieving quality library service delivery. The survey research design was employed for the study. The population consists 71 library personnel from two university libraries (Babcock and Tai Solarin Universities). Total enumeration method of sampling was applied as all members of the population were used for the study. Self-structured questionnaire was used for data collection. Data collected were analyzed using frequency and percentage count as well as mean and standard deviation. The study found that these libraries use competitive intelligence approach in their service delivery, however, may not necessarily be using new technological methods in their service delivery due to lack of funds, lack of ICT equipment, etc. Based on the findings, recommendations were made thus, that adequate provision of funds should be made available to libraries in order to purchase computers and other modern ICT equipment that will aid in effective quality service delivery and also help to gain competitive advantage over other libraries around. Secondly, libraries should create prompt awareness and guidelines of various services they offer; hence awareness of what is available could lead to its demand and use.
