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.
