I want to defend reprinting in chronological order. The Golden Age Superman is the most significant comic in history, and to watch the evolution of this character (at least until 1945 or so) is to watch the evolution of comic books themselves.
True, there is almost no continuity from story to story. But there is a definite continuity in terms of evolving the character, the art, and genre over the years. Nobody knew what a comic book was supposed to be, especially a superhero. Siegel and Shuster took certain elements of the pulps (which these early volumes read like: pulp stories), and certain elements of adventure comic strips (like Flash Gordon and Buck Rogers), and created an all-new genre. That evolution occurs in these pages.
The irony of Superman is that before WW2, certainly before Pearl Harbor, Superman is the symbol of the little man against the corrupt power structure in America. No, he doesn't challenge the system per se, just the evil people that it can produce. Remember, 1938 is steeped in the Great Depression and still conscious of the horrors of WW1 (among other societal problems and fears). The two greatest evils of that era were the corrupt big businessmen and the mafia. (Also throw in evil scientists and their killer gas! I think the Asian villain stereotypes like Fu Manchu had faded or began to wane by this time.) So Superman spends a fair bit of time dealing with these. But once WW2 starts, especially for America, Superman immediately grabs a flag and becomes a symbol of patriotism and the establishment. I don't think Superman again challenges an American status quo until the late '60/early 70s. (I'm not passing judgment on any of this. It's just how I see it happening.)
Another trend of early superhero comics is the utter lack of costumed supervillains. This is not a negative. This truly humanizes the character. It made him relatable because he cared about the problems regular people had. Plus, Superman's complete dominance really was the selling point. He needed no other superpowered characters to tell his story. Breaking steel bars and deflecting bullets were truly stupefying at this time. Kids loved just seeing him do that. Leaping over a tall building seems weak to us today, but kids everywhere marveled at the idea of jumping over a skyscraper. Forget Superman, the buildings themselves were marvels!
I've read Superman comics from virtually year of his existence. I love these early stories--despite any flaws or limitations--as much as any. And way more than the goofy stuff that dominates Superman stories (Kryptonite, Magic, and plot gimmicks) by the 1950s. My only caveat is that these reprinted comics were never intended to all be read at once. Comic fans know this, but new readers might not understand the difference between a graphic novel (one story) and a simple collection of stories.
I recommend this volume 100% and every volume in the series.
