Prior to answering the question regarding David A. Price's Love and Hate in Jamestown, the terms footnotes and references need to be defined (in order to identify them within a text).
A footnote an annotation made at the bottom of a page which provides information regarding a specific part of a text. This information varies; it can include omissions made from an original text, references to other texts, or historical information regarding an event named in a text. Footnotes are typically used by historians and texts written using the University of Chicago Manual of Style (simplistically called Chicago Style). A footnote appears as a numerical annotation appearing at the top corner following the information it is referencing.
A reference, on the other hand, is when a text includes information about another text, person, really anything. When this appears it includes an in-text parenthetical citation, a direct reference to the piece it is referring to, or a footnote. For example, if one were to discuss texts indicative of the Romantic Period, one could reference (bring up) Coleridge's "The Rime of the Ancient Mariner" or Shelley's Frankenstein.
In regards to Love and Hate in Jamestown by David A. Price, the text does not include footnotes, but the text does include endnotes (found at the conclusion of a text, not at the bottom of the page) and references (since they are inextricably linked). In fact, the first endnote used by Price is found on page 5. Here, Price references Peggy Lee's song Fever in the "Prologue." Price actually makes numerous references throughout his text and categorizes them by chapter.
