Two older works that still are frequently referenced in the historical literature with regards to the November Revolution are The German Revolution of 1918: A Study of German Socialism in War and Revolt by A. J. Ryder and The German Revolution 1917-1923 by Pierre Broue. Ryder's work largely focuses upon the SPD in the run-up to the revolution while Broue the various left-wing communist factions. Although both works are somewhat dated and reflective of scholarly mores of the late 1960s/70s, they are still important works on this subject.

Belinda Davis's Home Fires Burning: Food, Politics, and Everyday Life in World War I Berlin is an urban study that focuses upon the Kaiserreich's collapse from within. Using notions of gender, food consumption, and socioeconomic class intersected in wartime Berlin to create a mass crisis in confidence in the imperial government. The anthology Germany 1916-23: A Revolution in Context edited by Klaus Weinhauer, Anthony McElligott and Kirsten Heinsohn gathers together the work of recent historians on the Revolution. Like Davis, the contributors incorporate recent trends in scholarship such as transnationalism to understand these events in Germany and their wider global ramifications.

I wrote my senior thesis in my undergrad on precisely this topic. I'm not as informed as kieslowskifan seems to be, but I've got a few recs of my own to make.

Few things to know: The German Revolution, as an individually studied period in German history and as you have already observed, has few single volumes to draw upon. There are a variety of reasons for this, among them because historians think it more practical to look at the German Revolution within a wider context of the development of the Weimar Republic (and by extension, the Nazi takeover). Most questions asked of the significance of the German Revolution are going to be framed within those larger debates because otherwise, as a single event in German history, it bears little significance. kieslowskifan has recommended some very good ones, but I'll recommend a few more that were very helpful for my research too. Remember, some of the best writings on the German Revolution are not singly treated volumes but bigger works about Weimar and the coming of the Third Reich:

Eric Weitz, "Creating German Communism, 1890-1990: From Popular Protests to Socialist State", Princeton: Princeton University Press, 1997. First chapters are about the proto-communist movement in Germany (Spartacists, USPD, the creation of the Communist Party), the Revolution itself, and its importance in shaping the early history of Weimar. Any study of the Revolution will use this book, though it is a general history of German communism.

ed, David Barclay and Eric Weitz. "Between Reform and Revolution: German Socialism and Communism from 1840 to 1990". New York: Bergahn Books, 1998 (anthology). The David Crew article on Weimar social welfare was particularly useful to me since most of the questions surrounding the construction of a welfare state were often motivated by concerns about the potential for another workers' uprising and the experiences of the German Revolution. Communists and Social Democrats contested this space frequently.

Dirk Schumann, "Political Violence in the Weimar Republic, 1918-1933: Fight for the Streets and Fear of Civil War", New York: Bergahn Books, 2009. Good analysis of different leftist party cultures and how the revolution shaped these ideologies (as well as much of the discourse surrounding political violence during the Republic).

"All Power to the Councils!: A Documentary History of the German Revolution of 1918-19, edited and translated by Gabriel Kuhn. Oakland, PM Press, 2012. Nice translated compendium of good primary sources on the revolution.

Timothy Mason, "The Legacy of 1918 for National Socialism", in AJ Nicholls and E. Matthias (eds.), "German Democracy and the Triumph of Hitler", London, 1971. Tim Mason was one of the foremost historians on the working class under the Nazi state, but one of his most important theses was his idea that the machinery of of the Nazi state was influenced in part by the lessons of the German Revolution of 1918. It contributed to a belief held by some historians that the essence of National Socialism was its fundamentally anti-working class character. I would definitely refer to this article, even if it is trying to make a wider historical argument. Like I said, any good study of the German Revolution will address its wider historical implications beyond simply "this happened for this reason".
