Query: Not-such-a-great classic

Josephson is regarded as one of the semi-classic EP textbooks, but on the evidence of this edition, this may not be justified. The text is verbose, turgid and hard to read, and the numerous electrograms are poorly reproduced, making them hard to read and interpret. In retrospect, I'm not sure that this book was worth purchasing. The publishers need to clean up the text and improve the quality of the electrograms to make this a worthwhile purchase.
