Finding Journal Articles: Nutrition Research Guide

If a topic is too current or too specific to be covered by a handbook, encyclopedia, or book, it may be discussed in journal articles, research reports, or conference papers. Access to this literature has traditionally been through indexing and abstracting services. There is no universal index that covers all the published information in nutrition, so at times you may have to consult several sources.
