A primary source is a direct account from someone who experienced an event or person. A secondary source is an indirect account from someone who has acquired information from other sources in order to tell about an event or person. I don't know what book you are referring to, but I hope this helps!
This is a secondary source because it is evalulating tons of data in order to draw a conclusion about the issue. The source is not performing new research or experimentation but is commenting on existing information out there. Since this issue is regarding a technology that is not yet fully developed and because the research is still new, it is more appropriately covered by a secondary source. As a quality secondary source, it is able to compile myriad factors and studies in order to draw an interpretation or make predictions that might otherwise be impossible to see using only an isolated experiment.
I’m writing this letter to express my sincere gratitude for sending those books. I really loved them, they were very helpful I really appreciate it. Thank you so much.
