This book, together with the Sher "New Real Book" series are well done lead sheets. I think the Hal Leonard "Real Book" series has more of what I would consider the "old" standards (30s-50s), though there is a lot of overlap in titles between the series. I think you can check the index/table of contents online to see the titles included, to see if it has what you want. The Sher series seems to be a little more aggressive with alternative chords/progressions than the Hal Leonard series. The print is a little clearer, and there are lyrics included with many of the tunes (Hal Leonard Real Book series generally does not). Chord changes vary slightly between same tunes in the Sher and Hal Leonard series, but can't say that one is better or worse.
I bought both the Sher and Hal Leonard series, and am happy with both.
