The Reading Companion is provided by Hanoch Gutfreund, Director of the Einstein Center at the Hebrew University of Jerusalem, and Ju¨rgen Renn, Director of the Max Planck Institute for History of Science in Berlin. As those who have read (or attempted to read) Einstein’s book know, though the material is presented accessibly, it is certainly challenging, and the Reading Companion is a valuable and useful supplement to the text. It will be especially useful for those wishing to use Einstein’s booklet in teaching. The Reading Companion consists of thirteen commentaries, taking the reader systematically through the text.
