# Example1

According to scientists, the Sun is pretty big.[1] The Moon, however, is not so big.[2]

## Notes

1. E. Miller, The Sun, (New York: Academic Press, 2005), 23-5.
2. R. Smith, "Size of the Moon", Scientific American, 46 (April 1978): 44-6.

# Example2

This is an example of multiple references to the same footnote.[1]

Such references are particularly useful when citing sources, if different statements come from the same source.[1]

A concise way to make multiple references is to use empty ref tags, which have a slash at the end. Although this may reduce redundant work, please be aware that if a future editor removes the first reference, this will result in the loss of all references using the empty ref tags.[1]

## Notes

1. Remember that when you refer to the same footnote multiple times, the text from the first reference is used. Cite error: Invalid <ref> tag; name "multiple" defined multiple times with different content

# Example3

According to scientists, the Sun is pretty big [1]. In fact, it is very big [footnotes 1].

## Notes

1. Take their word for it. Don't look directly at the sun!
