In order to cite most resources, it is important to include an in-text citation and a reference entry. However, you will find throughout the examples that sometimes only a note is necessary for certain specified sources. ASA outlines how to include footnotes and endnotes:
Footnotes and endnotes should only be used when necessary.
Notes should be marked in the text with consecutive superscripted numbers at the beginning of the sentence to add explanations, limited citations, or additional information for a table. A parenthetical (in-text) note should be used for further references, such as (see note 2).
Footnotes should be in numerical order and double-spaced at the bottom of the page or in a separate Notes or Endnotes section.
For information on how to write footnotes and endnotes see section 4.5, p. 62 in the American Sociological Association Style Guide 5th Edition.
