This study was set to examine and identify some aspects of information literacy skills among postgraduate students at Sokoine University of Agriculture and determine challenges and problems facing them in terms of searching and use of various information resources. Systematic probability sampling and questionnaires were used to collect data from175 students out of 314 first-year postgraduate students registered. The findings showed that although information literacy exists among students, a good number of students demonstrated significant deficiency in their information literacy knowledge and skills in key aspects including searching for information from electronic sources, application of various information search techniques such as Boolean operators, use of truncation, synonyms and concept maps. Based on the findings, the paper recommends addressing the shortcomings found by introducing a mandatory information literacy course for both postgraduate and undergraduate students to ensure effective independent learning among students.
