Question

How should I cite this book in Chicago style? It has multiple authors and has been translated. This was my attempt:
Raynal, Maurice, and Lassigne, Jacques, and Schmalenbach, Werner, and Rüdlinger, Arnold, and Bolliger, Hans. 1950. The History of Modern Painting from Picasso to Surrealism. Translated by Douglas Cooper. Alberta Skira

Answer 1

For four or more authors, list all of the authors in the bibliography; in the note, list only the first author, followed by et al. (“and others”):

1. Dana Barnes et al., Plastics: Essays on American Corporate Ascendance in the 1960s . . .
2. Barnes et al., Plastics . . .
