Footnotes and Endnotes (The GNU Troff Manual)

#### 3.2.6 Footnotes and Endnotes

Footnotes and endnotes are forms of delayed formatting. They are recorded at their points of relevance in the input, but not formatted there. Instead, a mark cues the reader to check the “foot”, or bottom, of the current page, or in the case of endnotes, an annotation list later in the document. Macro packages that support these features also supply a means of automatically numbering either type of annotation.
