Additional Footnoting Information
Outside information (not common knowledge) should be footnoted. However, this does not mean you have to have a footnote at the end of each sentence. For example, you could paraphrase from one source for 3-5 consecutive sentences. You only need to give the footnote at the end of the last sentence to signify to the reader that all that information came from one particular source.
The example above that shows a footnote after consecutive sentences of paraphrasing. As you can see in the example, pages 16-20 in John Smith's book are paraphrased in 4 sentences (Note- the John Smith book is not a real book, merely an example) Appropriately, the footnote superscript number is not placed till the last sentence since it is consistently summarizing one source.
You always give a footnote at the end of the sentence after you give a direct quote.
