Reports which are not the responsibility of one individual should be listed under the name of the body responsible for their publication.
Note: corporate publications should not be listed under the name of the chairman of a committee, in spite of the fact that they are commonly referred to in this way.
Below is a sample corporate publication reference.
The Royal Marsden Hospital Bone-Marrow Transplantation Team. Failure of Syngeneic Bone-Marrow Graft Without Preconditioning in Post-Hepatitis Marrow Aplasia. Lancet 1977; 2:242-4.
