Whether you're quoting, summarizing, or paraphrasing a source, you want to make sure that you're not just dumping it into your paper with no introduction and no explanation of how it ties in to your research.
When you're writing a research paper, your voice is the most important - don't be drowned out by a bunch of quotes.
Use the ICE Method to help:
I ntroduce the source using a "signal phrase" - this goes before the quote (or summary or paraphrase) and introduces who the author or organization is and where the source came from.
C ite the source - this is where you put your quote, summary, or paraphrase. Make sure you add the correct in-text citation.
E xplain how this ties in to your paper/research in at least another sentence or two.
