Permits


Permits are documentation authorizing transactions such as
Accessions and Loans.
In general, permits are issued by governmental agencies, but letters authorizing
collecting activities on private land can also be considered permits.
Some “registrations” may also constitute permits.
For example, museums can do international exchanges of specimens of endangered
species if the museums are registered with their respective governments
under the Convention for International Trade in Endangered Species (CITES).
In this case, it is the institutional certificates of CITES registration
that constitute the authority.
Permits can can authorize any number of transactions,
and any number of permits may be required for a transaction.
