There is no "right" footnote or endnote number. The number of notes should relate to the length of your paper, the breadth of your research, and the nature of your conclusions. Here are a few examples:

• For a short paper (five to ten pages) that cites eight sources (books, articles, Web pages) and has a conclusion that is interesting but does not challenge your readers’ opinions, you should have somewhere in the range of ten to twenty footnotes or endnotes.

• For a long paper (fifteen to thirty pages) that cites eighteen sources and has conclusions that may be surprising or controversial, you should have somewhere in the range of thirty to sixty footnotes or endnotes.
