* KU Ichthyology has chosen not to use barcodes due to the cost per unit effort being too high. "Due to the fact that we only use barcodes for processing loans and inventories and process relatively small loans of material, the cost of adding barcodes to every jar (43,000 of them) far outweighs the gain achieved." from Andy Bentley (abentley@ku.edu) | * KU Ichthyology has chosen not to use barcodes due to the cost per unit effort being too high.
