Dear Fellow Archaeologists: We are currently trying to draft guidelines for curation of historic artifacts and are interested in how other institutions handle similar problems. Is 100% curation necessary? For example, what percentage of corroded and unidentifiable nails are retained ? What material classes, such as coal, can be counted, weighed, and then discarded in the field? Is there an industry standard for these matters? I am most interested in hearing your curation tales. Thanks for your help. Regards, Debbie Rotman Ball State University
