The constant change in technology, its impact on the electronic information environment and complex library users are forcing academic librarians to majorly change their skill set. Patrons no longer request for physical information but are accessing and retrieving information electronically. This study investigated the current training needs of librarians in Tanzanian academic libraries with the aim of developing microlearning intervention for training. Using a self-administered questionnaire, data were collected from 138 librarians in six Tanzanian academic libraries. Results identified the most important competencies and skills needed by the librarians and also identified barriers to librarians training. Identifying librarians’ training needs will accelerate the training required for the librarians to gain current expertise based on need. Using microlearning for training will eliminate the barriers to librarians’ training. Increasing training and learning efficiency is crucial if these academic libraries are to maintain relevance and continue to meet the needs of their users.
