Yes, Ian, I have much affection for the Penguin CD Guide.   In a perennial battle for a semblance of order on my bookshelves,  I now see that I have collected more than a dozen editions, over the years.  Initially, I treasured my New Pengiun Guide to BARGAIN Records, then the PG Guide to Cassette Recordings, and by the time of the changeover to Compact Discs, I had an ample contacts in London bookshops to obtain 'review copies' at half price.   Now, of course, DVDs have been included. 

Edward Greenfield, in particular, was always a first class guide and how I miss his gravelly tones on R3.   He always spoke with his own voice whereas, listening to, say, CD Review, I always sense that I'm getting an amalgam of every newpapaper or magazine review, rather than the assessment of the speaker.
