Arbeidernes Leksikon

The publication had a connection with the Norwegian labor movement's goal to spread knowledge among the working and lower class, and in doing so could break the monopoly the middle class had on the dissemination of information in society.

The idea of such an encyclopedia came within the group that produced the laborers' magazine Arbeidermagasinet.

Communist Party member Jakob Friis was hired as chief editor of the encyclopedia in 1930.

In April 1933, Arbeidernes Leksikon received a grant from the group Mot Dag, which had formerly been affiliated with the Communist and Labour parties, but now was independent.

Mot Dag leader Erling Falk was involved with the editorial work.
