The best introductory text on 1848 is the second edition of Jonathan Sperber's The European Revolutions, 1848 - 1851. Sperber wrote a very clear and comprehensive survey of the Revolutions that covers why they originated and how they failed. Much of 1848 historiography is dominated by events in Germany and revolves around what A. J. P. Taylor (stealing from Trevelyan) called "the turning point in history that failed to turn." The older historiographic line was that 1848 offered a chance at German unification under democratic auspices and the failure of the Paulskirche parliament meant Germany would unify under illiberal ideals that culminated into Hitler. This narrative has come under increasing attacks by historians such as Sperber in his Rhineland Radicals or Brian Vick's Defining Germany: The 1848 Frankfurt Parliamentarians and National Identity. 1848 was also a European-wide event and the anthology Europe in 1848: Revolution and Reform edited by Dieter Dowe, Heinz-Gerhard Haupt, Dieter Langewiesche, and Sperber is a thick (the paperback weighs over three pounds) and comprehensive discussion of 1848. The contributors to the anthology 1848-A European Revolution?: International Ideas and National Memories of 1848 edited by Axel Körner tack to a transnational approach to 1848 and have good insights into how 1848 failed to latch onto popular memory, hence the revolutions' absence in a number of history curricula.
