Q. If a portion of a book is quoted in text and the author and the name of the book are given in the text (e.g., “Sensory perception is a matter of selectively throwing away information,” write Terry Bossomaier and David Green in their book Patterns in the Sand), is there a need for an endnote, as well?
A. You do need a complete citation when you quote someone else’s work in text. It needn’t be in the form of an endnote, but an endnote (or footnote) is an excellent way to add the publication information (city, publisher, date) and page or location number of the quotation if you can’t squeeze it all into the text.
