Most of the comics have the name of the series in title. I think that, most of the time on comicogs, the title given to the comic is the one of the volume without the name of the series included, am i right?
In my opinion there's no need to have the series name in the title because "Explore" pages always show the series beneath the title (together with volume and issue). However, in that example it may be justified, although I'm not sure, for the reasons given in the description of how the series has been published in English, which does not conform with original series name, numbering or book content.
Yes that's true the series in english differs than in French. But i wonder what is the rule for the future of the DB, when (if) many comics will be registered here. We need a process.
