Under certain circumstances, material from the collection may be loaned to researchers for a period of six months. Loans are not made to individuals, but rather to the institution where the borrower works. In the case of loans made for student use, a faculty member at the borrowing institution (in most cases the student's academic advisor) must agree to take responsibility for the loan. Please note that the Department of Mammalogy does not normally loan primates or type specimens.

Application Process

Requests for loans of specimens should be made by completing a Specimen Loan Request and emailing a copy to Be sure to include complete contact information for the person requesting the loan, a brief project description including methods and goals, type of storage and security available for the specimens while on loan, and a detailed list of specimens and preparation type(s) you would like to borrow.

If you propose to undertake any destructive sampling of AMNH specimens, including making molds, you must also submit an application (with full justification). See the destructive sampling page for details.

If you are interested in borrowing tissues, please see the information about tissue loans on the the tissue collections page.
