Perhaps you should try some spelling variations:
"the urban bias series" » "the urban stias series", "the urban bias sources", "the urban atlas series", "the urban bus series"
"the urban two stories" » "the urban two studies", "the urban two theories"
"the urban o series" » "the urban 3 series", "the urban 2 series", "the urban 4 series", "the urban os series", "the urban _ series", "the urban a series"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("the urban o series") OR ("the urban bias series"))) OR ("the urban two stories")).
• Removing quotes may allow a broader search: (((( the urban o series ) or ( the urban bias series ))) or ( the urban two stories )).
• Adding a wildcard symbol may retrieve word variants: (((("the urban o series") or ("the urban bias series"))) or ("the urban two stories"))*.
