Classic Comics Library the title is published by Classic Comics Library the publisher. It's a series of trade paperbacks reprinting public domain comics from the 1930's to the 1960's. The subjects are different from issue to issue, but all have a Classic Comics Library issue number, making it a series.
Note on the cover dates: Classic Comics Library publishes this series through a Print on Demand service. They have a long list of books they want to put out, and they get numbered as they're added to the list. So they're not necessarily released in numerical order. They also release multiple books per month. Therefore dates will be all over the place, starting in 2015, and you may see multiple issues with the same cover date.
