One important aspect of letting your reader know that you have borrowed information from someone else is to use a verb of attribution. These verbs signal to the reader that the information is not yours.
For example if you wish to summarize what someone else has said on a particular subject you would state some like this:
According to the Mr. Jones, ice melts at a different rate in space then it does on earth.
The word, “according,” in this example is the verb of attribution. For a more detailed explanation and a list of examples use an internet search engine to search for “verbs of attribution.”
