Conclusions & Recommendations
• Scientometrics studies are important in informing LIS education, curriculum development, research and management of library services
• Recommendations – Many factors should be considered in combination when evaluating
the research performance of librarians and other scholars; should not consider the number of publications alone
– Publish in journals that are widely visible (e-journals & open access)– Increase level of teamwork in research & publication– Encourage mentorship between senior & junior library staff– Encourage students to publish with members of academic staff– Establish Tanzanian online journals in library science– Put more emphasis on teaching bibliometrics/scientometrics in LIS
schools because few studies have been conducted in Tanzania – Libraries should conduct bibliometrics/scientometrics of their
institutions
Study limitations
• The paper only focused on online publications that were retrieved by PoP through Google Scholar
• Papers that were published between 1984 and 2013
