There are many more types of children's museums working that are categorized in any list of museum types in museology theories. Also in the literature about children's museums hardly any distinctions is made among children's museums with clearly very different subject themes and goals. This has generated a situation that the name "children's museum" is used for museums and organizations that, based on their purpose and subject themes, should really be classified under other types of museums. Second part of this book looks at mission and vision statements of different children¿s museum.
