Perhaps you should try some spelling variations:
ethnographic videos » ethnographic visions, ethnographic models, ethnographic view
ethnographic codes » ethnographic models, ethnographic notes, ethnographic mode
ethnographic video » ethnographic view, ethnographic index, ethnographic mode

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: ((((ethnographic videos) OR (ethnographic codes))) OR (ethnographic video)) online, volume 1.
• Adding a wildcard symbol may retrieve word variants: ((((ethnographic videos) or (ethnographic codes))) or (ethnographic video)) online, volume 1*.
