The blue cover contains two booklets, an Urtext edition and a modern realization of the works by Schneiderhan. The Urtext is, of course, very nice and carefully put together based on the autograph score, although there are only a few notes on errors and ambiguities while the majority are "corrected" without comment. Thus, the autograph score should still be consulted. The Schneiderhan edition contains 1) bowings, 2) fingerings, and 3) practical realizations of chords and arpeggios. This edition is very useful for students who are unsure of how certain chords in the contrapuntal passages, whose actual execution may be impossible or impractical on the violin, should be played, including how long each note should be held. Of course, the text is a modern edition, and Schneiderhan's own performances are on the romantic side, so it is probably not so useful if you are interested in historically informed performance. However, Schneiderhan's edition gives very clear emphasis to the counterpoint compared to the standard Galamian edition. If I have a gripe, it's that the edition is sometimes too explicitly notated. For example the Ciaconna is nine pages, with the long arpeggio section taking up two pages alone.The paper quality is high and sturdy, and is a tan color to reduce eye strain.
