I bought the book to be able to read the actual text of "Mrs. Warren's Profession", which I had just seen. The texts of three other Shaw classics (Maj. B., Pyg., & Arms) were a fine dividend, hence my comment that the book is a good addition to the reference shelf. However, the accompanying materials were of decidedly mixed value. Shaw's notes, as usual, made good reading, and the quotes from contemporary performance reviews, especially for Mrs. Warren, were quite colorful. The rest of the articles, which I suppose are samples of Literary Criticism, made me glad I chose Physics as a profession. They were dull, turgid, and dry - academic English at its worst. I bogged down early. Of course, they are now decades old; fashions may have changed.
