Perishable Materials is an introduction to an often overlooked classification of artifacts. It provides individuals basic information on the recognition of perishables, cultural usage and alteration, and preservation.  Not all the material offered will be applicable to every field situation.  It is important to maintain at least a marginal working knowledge for the field experience that does involve perishable materials.
