Well, volume three is at least about a thousand times better than the first two volumes of this series. Mostly that had to do with Ann Nocenti's run ending and the other issues collected here being from other writers.
Inside the cover is says this was originally published in Green Arrow #0, #14-16; The Savage Hawkman #14; and Justice League #8 and #13. As a collection this is pretty problematic as you have a hodge podge of excerpts from larger stores that don't really connect to each other. So even though some of the issues are decent by themselves they just don't hold up together as a collection.
