Berlin's Central and Regional Library says it will return books the Nazis stole from the Social Democratic Party, including an English-language copy of the Communist Manifesto.
The copy dates from 1883 and is believed to have belonged to Friedrich Engels, who penned the original German work with Karl Marx in 1848.
The library said Monday the work is one of some 70 to be returned to the party on Aug. 31.
The Social Democratic Party was banned in 1933 after Hitler came to power.
Activists from the party continued to oppose the Nazis. Many were persecuted or killed for their activities.
