Loan requests must be made to the curator of the relevant collection. Curatorial contacts are listed below. The loan request must be approved by the curator before specimens are loaned. It is the responsibility of collection curators to judge the validity of the loan request, the credentials of the requestor, and the condition under which specimens will be used; they reserve the right to refuse loan requests. Staff members may not grant loans from a collection without the permission of the curator or adjunct curator of that collection.
