Archie Green's obituary takes on the standard obituary lead by focusing on one main "claim to fame" point of his life; the fact that he merged his university training and blue-collar work into a field of study all his own. The age of his death is incorporated into the story, instead of being blatantly stated as "he was 91," though. The second paragraph does state the cause of death, which was of kidney failure, and where he died, at his home.
Sources used within the story are primarily quotes from Green himself. There is one quote from an old friend, Robert Cantwell, which spoke about his character and how he viewed working men as important aspects to the culture of the day. Other than that, however, all of the quotes are either from interviews Green did previously or writings from his books. This is a good approach for this man because he was a self-made legend. He was interested in the working class culture and labor unions and made these things something for the rest of the world to take note of through his own studies. Other people cannot express what he wanted to do better than his own words can.
The lead works in this story because it is encompassing his entire life by pinning his university education against his other "working" education. He truly did merge both areas of his life into one field of study, which is not only his claim to fame, but is understood through the timeline of his life.
The obituary differs from a resume because a resume cannot indicate the impact his work has had. A resume would only list his accomplishments, where his obituary shows the impact he had, the work he did to create that impact and the way in which the world has taken his idea and run with it. It is not a straightforward list of accomplishments, but rather a melding of times in his life that were significant and what that meant in relation to his main goal of educating the world on a particular working class culture.
