What I mean is this: Releasing a magazine containing chapters of different series into a single "book" with some insights. Series can end at any chapter and a new one will replace it. Volumes containing a certain number of chapters from a certain series will be released as the series is complete with some bonuses. Do you think it will be commercially successful? And do you think it should be released once/twice/ or four times a month? Anyhow, a chapter continuing a certain series will only be a month later, so series will alternate if the magazine is published more then one time a month.
