Yep, they have reprinted a ton in that format. Those books are durable, easy to read, and done with the best reproduction available.... but the flipside they are god damned expensive.
You can see how many different series they've collected in this format & changes they've made to the books along the way here: https://en.wikipedia.org/wiki/Marvel_Masterworks
Golden Age: 9 different titles (30 volumes total)
Atlas Age (1950s to pre-Silver 60s): 10 titles (28 volumes)
Silver/Bronze: 40 titles (243 volumes). Some interesting choices here other than the aforementioned Howard... who would have guessed they'd Masterwork Dazzler? Champions? Deathlok? Rawhide Kid? All have gotten at least one volume done. I guess in some cases (Champions for sure) it collected the entire series.
