All of the reference types, except for Generic, can be modified using the Reference Types preference. Whenever you make a change to a reference type, you should also edit your styles to make sure that they correctly format the new or modified reference types.
If you plan to share your libraries with other users, you may want to limit the use of new and modified reference types.
The Reference Types table applies to all libraries opened on a computer from your user account.
If your library is opened from a different computer or a different user account, your references will follow the layout of the Reference Types preference for that computer and user, unless you also transfer a copy of your reference type table. See Sharing Your Reference Type Table.
If you modify a reference type for records in your EndNote library, you should make sure that the reference type is also created or modified on other computers that will access the library.
Do not try to edit the Reference Types preference to rearrange information within your references. For example, if you delete the "Journal" field and retype "Journal" elsewhere in the column for Journal Articles, you are telling EndNote to close the original "Journal" field and display a new field called "Journal" in another location—this does not move your data from the original "Journal" field to the new one. Any references that had data in the original "Journal" field will still show that information, but the field will have its "Generic" name of "Secondary Title." The new "Journal" field will remain empty.
