TEEAL is a digital library (www.TEEAL.org) that has revolutionized agricultural research in the developing world ranging from Asia and Africa to Latin America. The Albert R. Mann Library at Cornell developed the library in 1999, working with important publishers and with funding from such organizations as USAID, the World Bank, UNESCO, and the Rockefeller Foundation. TEEAL provides digital access to more than 200 peer-reviewed international journals from some 60 major publishers. TEEAL has spread throughout Africa largely through the efforts of the Information Training and Outreach Centre for Africa (ITOCA) which has served as a marketing and support agency for Mann in Africa. Emeritus Professor Royal Colle interviewed Gracian Chimwaza, ITOCA's executive director, during the 2013 World Congress of the International Association of Agricultural Information Specialists, which was hosted by Mann Library. In this interview Chimwaza discusses the positive impact of TEEAL on researchers, faculty and students, the significance of new information technology in fostering the adoption of TEEAL in African countries, and the on-going relationship of Mann with ITOCA and the African community of agricultural scholars. Throughout the interview, the library is referred to as "TEEAL" which is the acronym for The Essential Electronic Agricultural Library.
