Perhaps you should try some spelling variations:
"the urban studies series" » "the urban studies services", "the urban studies species", "the urban studies theories"
"the urban bias sources" » "the urban beams sources", "the urban iras sources", "the urban gas sources", "the urban bus sources"
"the urban stias series" » "the urban atlas series", "the urban series series", "the urban skills series", "the urban soils series", "the urban spas series", "the urban spatial series"
"the urban alias series" » "the urban atlas series", "the urban pandas series", "the urban alias harries", "the urban areas series", "the urban aerial series"
"the urban bias series" » "the urban atlas series", "the urban lucas series", "the urban bus 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 bias series") OR ("the urban bias sources"))) OR ((((("the urban stias series") OR ("the urban studies series"))) OR ("the urban alias series"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"the urban bias series\") or (\"the urban bias sources\"))) or (((((\"the urban stias series\") OR (\"the urban studies series\"))) or (\"the urban alias series\"))))*".
• Removing quotes may allow a broader search: (((( the urban bias series ) or ( the urban bias sources ))) or ((((( the urban stias series ) OR ( the urban studies series ))) or ( the urban alias series ))))*.
