By default, all sources in your project are exported when Print/Export is selected. However, if you want to use only selected sources in your exported bibliography, you can tell NoodleTools not to include the source in the final reference list. Here's how to do it: 

  1. Next to the source you want to leave out of the reference list, on the Options menu, select "Edit." 
  2. On the citation form, scroll to the bottom. 
  3. Uncheck the box "Include this source in my final works cited." See below image.
