Perhaps you should try some spelling variations:
"biblioteconomia i administracio cultural ;" » "biblioteconomia i administracio local ;" (Expand Search)
"biblioteconomia dret administratiu local ;" » "biblioteconomia dret administracio local ;" (Expand Search), "biblioteconomia dret administracion local ;" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"biblioteconomia i administracio cultural ;\") OR (\"biblioteconomia dret administratiu local ;\"))~".
• Removing quotes may allow a broader search: (( biblioteconomia i administracio cultural ; ) OR ( biblioteconomia dret administratiu local ; ))~.
• Adding a wildcard symbol may retrieve word variants: (("biblioteconomia i administracio cultural ;") OR ("biblioteconomia dret administratiu local ;"))*.
