For each item you selected, write down a concise summary of what it contains, and how it will inform someone. If appropriate, add evaluative comments telling what is or is not covered, any strengths or weaknesses you notice, and where it might fit into an overview of your topic. Note the author's experience and qualifications in their field, or lack of it.
[STEP 1] Smith, John."Causes of the Russian Revolution." Critical Essays on the Russian Revolution, edited by David Fry, MIT Press, 1973, pp. 91-133.
Smith, [STEP 4] a Russian history professor at USC, based his research in this book chapter on documents discovered in the early 1970s. He reveals that a few Germans played a key role in the events leading up to the revolution. They provided money, arms, and leadership that helped the revolution get started. Smith's conclusions are radically different from those in Mark Johnson's Why the Red Revolution? However, Smith's case is [STEP 6] somewhat weakened by an anti-German bias, which was mentioned by two other sources. [STEP 3] Smith addresses himself to the scholar, but the language will be clear to any informed reader. The style is heavily argumentative, with [STEP 5] many footnotes to back up claims. [STEP 2] It is relevant to the research topic, specifically how anarchists played a role in the Russian Revolution. It is especially useful for its information on the action and attitudes of the anarchists. This chapter is cited by other writing about the Revolution, but is considered controversial.
