I'm trying to import the book which I found in a Catalog search into EndNote.
To import a catalog record into EndNote, click on the EndNote icon in the upper right hand side of the page and save the file. Then, go into EndNote and select File-Import. For the Import Data File, browse to wherever you saved the catalog record (my default is to save to my desktop). For the next box down, Import Option, choose "Reference Manager (RIS)". You'll have to go to "Other Filters" if it's not in your drop-down list. After these two steps, click Import at the bottom of the box. Your file should come in just fine.
Another way to do this is to search the Catalog from within EndNote. Under Online Search in the left menu of your EndNote library, you should have a UNC-Chapel Hill search option.
