A study was conducted to investigate the accessibility and use of e-resources in Tanzania. The methodology adopted for the study was survey in which questionnaires, interviews and observations were used in collection of the data. A total of 50 respondents participated in the study. The study revealed that livestock research institutes in Tanzania had very few e-resources for their researchers. It was concluded that most livestock researchers were not aware of most of the e-resources available hence they could not access and use them effectively in their research work. The researchers recommended for improvement of internet connectivity to enable efficient information searching from the internet.
