Publisher information is contained in the publisher element, with the name of the publisher in the publishername element and the address of the publisher in the optional address element. publishername can also be the name of a web site or other, less formal, publisher.

For some resources, for example personal communications, publisher can be omitted.

The address element can be used with plain text if the address is simply the city, city plus state/province, or city plus country. I recommend that if it goes beyond this simple use (or even if it is that simple), that the child elements be used. This is particularly helpful if the markup contains a full street address, since styles typically don’t use street addresses. Using the child elements lets the processor decide how much of the address to use. See Open Question 8.
