The editor and the translator of this volume are heavily indebted to many other scholars. Very useful advice on specific points was offered by Alessandro Lazzari, Alexander von Schönborn, Angela Smith, Christian Johnson, Daniel Breazeale, David O'Connor, Doris Jankovits, Eric Watkins, Faustino Fabbianelli, Fred Rush Jr., Gary Gutting, George di Giovanni, Günter Zöller, Lara Ostaric, Manfred Frank, Marcelo Stamm, Martin Bondeli, Megan Halteman Zwart, Noell Birondo, Paul Franks, Sabine Roehr, and Stephen Dumont. The translation benefited especially from the help of Susanne Hebbeler, and some very difficult points in Reinhold's notes were clarified by Andrew Rosato and Patrick Gardner.

In comparing the two versions of the text and working out the best way to display the complex relation between them, the editor was fortunate to have the invaluable advice and assistance of the translator, James Hebbeler. Encouragement and advice from Hilary Gaskin at Cambridge University Press were of enormous help throughout the project.
