A book chapter from an edited volume is entered as a “Book Section”. Click the green new item button and select “Book Section”. You will now see both a “Title” field for the chapter title and a separate “Book Title” field. To add an editor click the + sign on the author line in the right column. This will create an additional Author line. If you click the triangle to the left of the new author field you will be able to change it to an editor.
