According to Bernstein, the New York Draft Riots started on July 13 to July 17, 1863. The riot which started as a protest soon degenerated into a violent disturbance. The people initially angry about the National Conscription Act were attacking the African-Americans and the poor. The website is also stating the same event, but explains it more. It describes exactly what was happening each day during that time. The rioters where attacking mostly African-Americans, took their properties and it is sad that some even lost their lives.

Both of the sources were reliable and very helpful as they are explaining what happened during the Draft. As far as which one was best to me, I will definitely opt for the website, because I think they explain the situation more, I was able to see phase to phase what happened each day till the end. It was very clear, and easy to go trough.
