Quality library service depends partially on librarian capability and the adoption and use of technologies that enhance productivity. The perceived adoption and use (PAU) of electronic records management (ERM) in archiving were investigated in four academic libraries in Djibouti. The effects of capability of Librarians to use ERM (CAP) on knowledge sharing (KS), the effects of CAP on PAU, and the mediation potential of KS on the relationship between CAP and PAU were studied using structural equation modeling-partial least square design (SEM-PLS). Findings showed that CAP weakly influenced PAU, but did so significantly when considered with KS. This confirmed the mediating potential of KS. CAP also positively influenced KS among Librarians. The weak effect of CAP on PAU could be further investigated by considering other factors that define both library and personnel capabilities for ERM adoption. The study implied that KS should be practiced along with capacity development of Librarians in order to enhance PAU in Djibouti’s libraries.
