In 1937 A. E. Douglass, founder of the modern science of dendrochronology, established the Laboratory of Tree-Ring Research at the University of Arizona. The Tree-Ring Lab is recognized worldwide as a preeminent center for the advancement of tree-ring techniques and the broad application of dendrochronology in the social and environmental sciences.
The Tree-Ring Lab collections and archives includes reports published by the Laboratory, which have been digitized and made available in this collection.
