|In a 1969 talk at the Smithsonian, Archer warned that while
presidential, war, and literary materials were often deposited in libraries,
"biological material, and especially that of botany, meets with scant interest."
He also told of many botanical manuscripts and field notes that were lost
or thrown away - including 12,000 transcript cards concerning "all published
data on the medicinal uses of plants by American Indians." The cards were
moved to an attic, then later used as swamp fill. Missouri Botanical Garden
