Subject searches use pre-determined, offical vocabularies.
Separate subject divisions with double hyphens. If you have difficulty, try a keyword search instead. Then determine the offical subject terms from the records found. It does not matter if you include the periods or not. Keyword Searching Searching by keyword gives you added search capabilities and more flexibility.
