Identify the source. List the author’s name and a shortened title of the source, and a page number, if available. Your working-bibliography entry (17b) for the source will contain the full bibliographic information, so you don’t need to repeat it in each note.
Indicate whether the note is a direct quotation, paraphrase, or summary. Make sure quotations are copied accurately. Put square brackets around any change you make, and use ellipses if you omit material.
