The first volume was released on a biweekly basis and lasted for 175 issues. Each issue had four eight-page stories, of which generally two were episodes in ongoing serials and two were one-episode stories. The one-episode stories generally featured obscure or little-seen characters from the Marvel universe.
The original plan was for the lead story to feature different members of the X-Men in solo adventures lasting between eight and ten episodes. The first ten issues featured Wolverine, others to be featured were Colossus, Cyclops, Havok and Excalibur. From issue 39 onwards, Wolverine was featured as the lead story in all issues. Particularly noted was the Weapon X story in issues 72 to 84 which re-told Wolverine's origin with story and art by Barry Windsor-Smith. Later Ghost Rider was added to the series as "co-lead" feature and the book adopted a "flip-book" format, thereby allowing each of the two characters cover billing. Eventually other characters, such as Man-Thing and Lunatik, got cover billing.
This torrent was inspired by Nerone's X-Men chronology. I noticed that his issues of MCP had all non mutant material removed. I thought to myself, why not take it one step farther and combine every multipart story into one volume? So I did. I plan to (as long as I see interest from downloaders) continue releasing these, Ghost Rider and Black Panther will be next, then I'll hit anyone else who had multipart stories, then finish up with the solo stories. I am aware that some of these Wolverine stories have been reprinted in a tpb, but I would assume that never got scanned, being pure reprint material.
Oh, and as far as covers go, I tried to grab the first issue of the run that featured that character on the cover, unless one of the other covers had a more iconic image. This will become exceedingly difficult after Ghost Rider, as he and Wolvie dominated the covers in this series.
