Are all of the volumes the same story or is it like, a series of related stories? Different volume names confused me.

It's hard to guess the timeline from the names, but yes it's all the same story. The volume name points at what character is mainly the volume about, like Nekomonogatari it's about Hanekawa Tsubasa and her "Neko" problems.

Just read this.

All of them are related stories. And instead of creating an individual page for each of them (as is customary) for some reason, the one who created this page did not follow mangaupdates standards and put all novels in the franchise in the same page for God knows why. In this website, there is something called "Related Series" and that's where you put all the related series, not cram all the novels/manga of a franchise in the same info page, for Heaven's sake! I don't even know how this got approved, to be honest. First of all, there is no "monogatari" novel. That's an informal term to refer to all the franchise of related novel series, not the official name of any novel. So it's not 'Monogatari (Novel)' but 'Monogatari (Franchise)'.

So please, could any moderator/administrator fix this page and create an individual info page for the individual novels? For example, one for Bakemonogatari (2 volumes), Nisemonogatari (2 volumes) and so on...

The series info page has already been renamed Monogatari (Novel) ... could be renamed (Novel Series).
Doing one for each is just excessive. It's fine the way it is now. Just gotta apply the change to the forum title.

Excessive? WHY? That's what you do for every novel/manga series. Also, "Monogatari" is NOT a formal, official term for the franchise, that's why nobody uses it formally in any encyclopedia/database since again, it's an informal term.

If you think fixing this is "excessive", then do the same with all the manga/novels in this site so all it's congruent. Remove the "Related Series" section and cram all the related series into one big information page. For example, for the To Aru franchise erase the info page of all the novels and put the informal term "To aru (Novel)" as title and cram all the related novel series in it like it is done here, so it's so messy and disordered that people trying to get some sense out of it will have to create topics like these so other members refer to them to other sites where the information is not all chaotic and cluttered like it is here. Is that what you're trying to say, FormX?

Check Wikipedia again. You'll notice that the novels are grouped under the heading: 'Monogatari Series' (that goes for the Japanese language version of the wiki too).
