These days of web-information literacy, universities in Nigeria lay emphasis on research productivity of academics. This paper is a descriptive survey which verified the extent to which web-based information literacy has enhanced the research productivity of the academics. The study was carried out in four Nigerian universities (two federal and two state universities). Three research questions and three hypotheses guided the study. The sample size was 480 academic staff drawn from the population of 2885. The instrument for data collection was a 24-item questionnaire structured by the researcher. The instrument was face and content validated and its reliability was computed to be 0.82. The data collected were analyzed using mean and standard deviation to answer the research questions and t-test statistics in testing the null hypotheses at 0.05 alpha level. The findings indicated that; WBIL has enabled research productivity of academics in both federal and state universities, lack of funds and dearth of technological equipment were among the administrative constraints while lack of web-based competence and academic overload were among the individual factors that hinder WBIL of academics. Provision of research grants and technological equipment were among the strategies for improvement in the usage of WBIL. Based on the findings, the recommendation among others, was that the university authorities are to provide free access to the internet connectivities to the academic staff for enhancement of research productivity of both federal and state universities in Nigeria.
