It looks like DC Comics are using the Omnibus format as their current way to collect classic material in chronological order. In the past, there have been the Archives series (hardcover, full color), the Showcase Presents series (softcover, black and white, usually twice the page count of an Archive), and the Chronicles series (softcover, full color, smaller page count than an Archive). In the past few years, all of these lines have been quietly shuttered, and now DC is releasing Omnibus collections in both hardcover and softcover formats.
As you would expect, the Omnibus hardcovers are huge. Two Silver Age volumes collected the first 76 issues of JLA (along with Brave and Bold 28-30 and Mystery in Space 75), for example. Earlier this year, DC released JLA: The Bronze Age Omnibus Volume 1, collecting JLA # 77-113. That's almost half of the original series collected in this way, which for a fan like me is great news. The JLA Archives had 10 volumes, collected the first 93 issues, and the first volume and last volume were released twenty-two years apart. The first JLA Omnibus came out in 2014.
DC is also releasing these collections in trade paperbacks with a smaller page count than the hardcovers. The great thing is that these TPBs collect more issues than the Archives did! The material collected in the first JLA Silver Age Omnibus has all been released in 3 TPBs.
I have the first JLA Silver Age TPB, and I loved it! I also have the first JLA Showcase Presents, but I find that without color, I just don't enjoy the stories as much as I could. Actually, I find I enjoy most Silver Age comics more in color versus reading them in Showcase Presents and Essential Marvel.
I wonder how many of the rest of you are buying and reading these Omnibus collections, and what you think of the format.
"...but where do you draw that line?"
Here's how it breaks down (roughly) or me:
Anything beyond that is "Modern Age"
Regarding an Adam Strange discussion, if someone else wants to start one I will commit to following/reading along; if it's up to me to lead it, it will have to wait until my Green Lantern discussion gets to issue #75 at least.
Just to prove that I'm not always negative, I just got the Spectre Omnibus, and moved it to the front of the line, and although I've only read the first couple of stories, they are as good as I remember from decades ago. I'm impressed that for the mid 60s they were probably as "creepy" as Fox thought he could get away with (and in spite of the fact that Anderson was probably not really the best artist for this kind of story), and based on my dim memories I'm anticipating that things will only get better.
I have been working my way through The Wrath of the Spectre omnibus, too. So far I've read through #4 of his solo series and plan to post something more comprehensive when I've finished (but my priority right now is Green Lantern). I had heard very negative things about the '60s series, but so far I'm really enjoying it. Some time ago I bought the Essential edition just so I'd have it in some format, but was never motivated to read it in b&w. I'm glad now I waited for the color.
Waiting to read-along on Adam Strange is fine with me. Reading his omnibus isn't the only thing I'm doing, so I'll get a bit of a head start.
