For research, sources matter, citations are more than just a means of avoiding plagiarism. Citations can show how ideas are formed and originated, and most importantly when the citations are read thoroughly to obtain a deeper understanding of the subject matter, what was once known, and may have fallen out of modern literature can be brought back into the light. There are many examples of this, but it is always important to under what the authors had been envisioning, as was very eloquently put by Prof. Tizhoosh. [1]
