Have waited years to get the CD of this, (I've owned the vinyl since the original month of issue) then five come along at once! Slightly to my surprise all these albums are of excellent sound quality. Comparing favourably with the originals when ripped and streamed.
Good Undergraduate text. Takes you from 'A' level M3,4,5 to final year probs. Not always painlessly but with non-patronising clarity. Read the first three chapters before going through the Introduction.
