Doctor Nagelius' Encyclopaedisches Compendium

User Summary: "Doctor Nagelius' wohlfeiles und weitschweifiges, exzentrisches und ekletisches Encyclopaedisches Compendium der bekannten Welt" (full name) is more an encyclopaedia of the 1880s than a roleplaying sourcebook. It covers everything from history, politics, arts, traffic, life stiles, biographies, science and more like this. It is written for Midgard 1880, but could also be used for any other Victorian role playing game.
