Thanks very much for the info. It looks like Vol 10 starts in the early Bronze Age and at just the end of Adventure Comics when they were no longer a cover story in Adventure Comics.
Makes me wonder if Vols 1-9 cover some to all of the Silver Age. Granted there are still some noticeable blank runs in the DCU Silver and Bronze Age sections, so redoing them digitally here wouldn’t likely work, at least at present. And if the trades are still selling well, there is no need, from a business standpoint, but hopefully the back catalog will get filled in and in maybe another decade, digital versions of these could be a possibility.
(I grew up on silver age Adventure Comics LOSH comics cuz they were much easier to find in the old 3 for a quarter boxes at the swap meets and often easy to haggle done to 5 for fifty cents or 12 for $1.00. While not always as interesting/complex as the Bronze Age stories, they were complete escapist entertainment I think of fondly.)
Thanks again for the info. Much appreciated.
