I like Kim's reference but agree with Phil that it's pretty difficult to know what to suggest without further context.
As for Geschichtsaufarbeitung and Vergangenheitsbewältigung, I hope you can read pp. 101-104 of "Geschichtspolitik in der 'Berliner Republik': Konzeptionen und Kontroversen" (Google Book preview). The former is more about what impact the past has on the present. That kind of approach seems to have originated with Theodor Adorno, who--despite the title of his work--"rejected the contemporary catchphrase 'working through the past' as misleading, observing that 'its intention is to close the books on the past and, if possible, even remove it from memory.'"
("Presenting Difficult Pasts Through Architecture" by Manuel Becker)
Also, I believe the following article is a worthwhile read:
