You are right in seeing this as an exception to the general restriction against non-accredited users and feeling that uses must therefore be fairly tightly restricted. This area has been one in which museum members of MESL found they really had to compromise, because University libraries are open to walk-in members of the public often and it is completely impossible for the universities to monitor what those people do. Universities felt strongly that this was part of their mission. Museums, of course, feel equally strongly that they do not want to lose control over the documentation of these works. We found that universities were willing to limit uses of the "library" when accessed from public terminals in the ways Mikki suggests - only "reference prints" (defined as low resolution screen images, almost certainly limited to black & white) and no downloading from these workstations.
   As with the rest of this discussion, we assume that if AMICO members agree to the principle here, the actual wording of this use restriction will be left to the lawyers. It is useful however to add as many specific allowable and disallowable uses as we can. Examples are very helpful in this essentially new realm of license agreements.
