This article provides the history underlying the journal impact factor and weaknesses of this measure to evaluate journal quality. The Eigenfactor and Article Influence Scores are suggested as an improved way to compare research quality and impact across disciplines. The network analysis underlying the Eigenfactor approach suggests the agricultural and natural resource economics profession can have a larger impact on the scientific community by directing more research effort towards interdisciplinary work. The Article Influence approach is used to develop a seven-tier system to evaluate research quality, to be used either to guide individual faculty about where to publish their research or to evaluate the research portfolio of a department.
