Index labels and examples of an expert search in WorldCat.org and WorldCat Local
- You may type an index label with your search terms rather than a selection from the list of indexes to search on any search screen. The information you type overrides all default menu selections.
- Use a colon after an index label (as in au:wang) when you are not certain of your search terms.
