Loan Requests

Guidelines for loans from the Herbarium

The Herbarium grants loans of specimens to institutions for study by affiliated individuals. The borrowing herbarium has the responsibility for the secure custody and proper return of the specimens. Specimens may not be removed from the institution to which they were loaned without prior permission and appropriate paperwork. By accepting a loan from MICH, recipients consent to study the material according to the following guidelines:

  1. All loan requests must be addressed to the Director (Paul Berry – peberry@umich.edu) or the Senior Collection Manager (Richard Rabeler – rabeler@umich.edu). Because the loan is under the responsibility of the receiving institution, the request must come from the Director of a unit or the Curator responsible for a unit. All requests must be approved by the Director of the University of Michigan Herbarium (or Assistant Director in his/her absence). The Herbarium reserves the right to restrict the size of loans or to decline a loan request.
  2. The normal loan period is two years unless otherwise specified; this may be extended upon request. We reserve the right to request the return of loaned material at any time.
  3. Loans must be stored in insect-proof herbarium cabinets at all times, except when being studied actively.
  4. All portions of the specimen must be returned, except those tissues consumed in DNA extraction or other types of morphological studies where prior permission was given to remove material. For removal for study of any part of the specimen (see our Destructive Sampling Policy).
  5. Type specimens: We are currently scanning our type specimens. As of January, 2010, all type specimens of flowering plants and gymnosperms are available for viewing at different resolutions as part of the on-line type collection. We encourage researchers to use our digital images whenever possible; type specimens are available for loan only by special request.
  6. All annotations and notes must be made with archival-quality ink on archival-quality paper slips and returned with the specimens. Annotations should be attached to sheets with archival-quality glue or inserted in packets or boxes. Loans must be annotated unless prior permission was given to return material without annotations.
  7. We welcome additions to the information documenting our specimens. If the specimen has been georeferenced, or additional or supplemental information is available from a duplicate with more complete label data or another source, we would greatly appreciate receiving this information.
  8. Loans may not be transferred from the borrowing institution without the prior permission of the Director.
  9. International loans including CITES-listed taxa can only be sent to institutions listed in the CITES Register of Scientific Institutions.
  10. The University of Michigan Herbarium should be acknowledged whenever its collections are used. Reprints or copies of any reports or publications resulting from their use should be provided to assist MICH in curating returned loans and documenting collection usage.
  11. The Herbarium makes no express or implied warranty as to the accuracy or completeness of the label data or identifications.
