In 2004, Mann Library, with funding from the Rockefeller Foundation, carried out a TEEAL User Study to evaluate whether TEEAL was meeting its objective of enhancing the quality and effectiveness of agricultural research and teaching by improving students' and researchers' access to relevant literature. The study collected qualitative and quantitative information, both through interviews with users and non-users at 10 institutions in 6 countries in Africa, Asia and Latin America and through a survey questionnaire of over 100 TEEAL users at 16 institutions in 9 countries in those same regions.
The interviews and survey asked a number of different questions to probe users' perception of TEEAL and its resources. In the survey, almost 80% of respoondents said that TEEAL improved their productivity and about 75% agreed that it improved the quality of their work. Users, who were largely research scientists, university faculty and graduate students, found that TEEAL's resources are both relevant to and adequate for their needs, and they trust the articles in TEEAL.
