If you wish to limit your search by location, use the location drop-down list. Choosing no location searches all locations. "In process" signifies that the item is being catalogued and is not yet available.
The Keyword field searches all fields. Use *
as a wild card character: car* finds car, cars, cart, Carnegie, etc.
Use & and / for "and" and "or" searches. For example, history & education will look for both words in a record whereas history / education will look for either word.
