The study tested a hybrid model with constructs drawn from the Technology Acceptance Model (TAM) and Diffusion of Innovation (DOI) theory in order to examine the moderating effect of productivity and relative advantage (RA) on perceived usefulness (PU) vis-à-vis electronic information resources (EIR) adoption in private university libraries in Ogun and Osun States of Nigeria. The descriptive research design was adopted in the study. The population consisted of 61 (55.0%) librarians and 50 (45.0%) library officers (totaling 116—100%) in Babcock University, Bells University, Covenant University, Bowen University, Oduduwa University, and Redeemer's University. Purposive sampling procedure was adopted after which total enumeration was used since the total population is small. The questionnaire was used for data collection. Of the 116 copies of the questionnaire administered, 111 (95.7%) were found usable. The instrument was structured based on a 4-point Likert agreement scale of Strongly Agree, Agree, Disagree, and Strongly Disagree. Data were analyzed using descriptive statistics like tables of frequency counts and percentage. The findings revealed that productivity and relative advantage are significant moderators of perceived usefulness of EIR adoption in private university libraries in Ogun and Osun States, Nigeria.
