Are the contents of the magazine volume the same as the standalone volume?

It was different. The contents of a magazine's bound volume and a separate volume usually differ depending on the type of magazine and the publication cycle. A bound volume was usually a collection of magazines printed separately. The cover was usually marked with the word "bound". A bound volume usually contains the content of multiple separate volumes but may be modified in terms of typography, illustrations, etc. to better suit the needs of readers. In addition, the combined volume may also add some additional chapters or short stories to meet the needs of different readers. In contrast, a standalone edition is usually an independent magazine that prints the work of only one author or editor. The content of a standalone edition is usually different from that of a bound edition because of the publication cycle and other reasons. The content of a standalone edition is usually published faster. Therefore, the content of the magazine may be different depending on the type of magazine and the publication cycle.
