My growing network of web sites currently consists of more than eight milliion pages, interspersed among several of my domains. It is a labor of love, and it reflects my passion for all things international. It developed over time in response to the innumerable e-mails I received from students, teachers, parents, children and others with questions about a particular country or the world.
