It's easy to modify an existing reference type in EndNote. Whenever you make a change to a reference type, you should also edit your Output Style to make sure that they correctly format the modified reference type.
Step One - Modify your Reference Type
- Go to Edit > Preferences > References Types > Modify Reference Types.
- At the Default Reference Type drop down menu select the Reference Type to be modified.
- Rename the relevant fields in the right hand column.
- Type a new name in the blank cells that matches as closely as possible to the Generic column in the left hand side eg for a map use Cartographer instead of Author.
- To save the changes select OK. This will return you to the Preferences box and select OK again to save all changes.
