Specific Rules #3 for Place of Publication (required) for Entire Books Vancouver Style: Multiple places of publication

If more than one place of publication is found, use the first one or the one set in the largest type or in bold type. Do not give multiple places.

An alternative is to use the place of publication and publisher likely to be most familiar to the audience of the reference list. For example, use the place of an American publisher for a US audience and a London publisher for a British one.
