1.  Specimens are sent on loan for a period of twelve months; an  extension may be granted upon written request to the Head of  the Herbarium Lucanum.

2.  Loans should be returned at the earliest opportunity and  preferably in their entirety. If, occasionally, borrowers wish  to retain certain specimens for further examination after the  return of the majority, they should only do so if these can be  studied in the near future; in all other cases they should be  returned and requested again later.

3. Specimens must be carefully packed to avoid damage in transit. The packing boards and folders in which herbarium specimens are sent should be used when they are returned.

4. Herbarium sheets must not be bent, folded, or laid face downwards.

5.  Specimens may be dissected or micro-sectioned only when the material is in sufficient quantity to permit this without prejudice to the future value of the gathering. A representative selection of all dissected portions, including micro-preparations, should be adequately mounted, labeled, and returned to the Herbarium Lucanum. Duplicates of all pollen slides and electron micrographs should be sent to the Herbarium Lucanum.

6.  Material preserved in liquid must not be allowed to dry out.

7.  Wherever possible specialists are requested to confirm (or redetermine) material sent. All annotations should be on small labels, signed and dated. Do not alter or obscure existing labels and annotations.

8.  Under no circumstances should cellulose self-adhesive tape or labels be attached to herbarium sheets.

9. Researchers are asked to send to the Head any publication which results from the study of borrowed material.
