You're a stronger person than I ... I tend to be really reluctant to give up on books once I've got beyond a particular point, even if they're really grating on me. I think I've got to stop reading books about librarians that aren't written by librarians, as there appears to be something of a trend of magical libraries at the moment, and it's rarely executed well. (I particularly could have done without the implication that all librarians are just failed or aspiring authors.) Given one of my most formative moments in a work of fiction is the point in His Dark Materials which prompts the quote 'tell them stories ... just tell them stories, and all will be well,' you'd think I'd have more patience for books about the magical power of stories, but I'm just finding them unbearably sentimental in the worst possible way at the moment.

I hadn't heard of any of your potential nominations, but I don't necessarily think it's a requirement to reread the books unless you're planning to write in those fandoms as well. I don't know if you nominate to request, to offer, or some combination of the two. (As for me, I nominate to request, because I know that it's almost certain that no one else will request a fandom I've nominated, and there's usually a bunch of other things in the tagset that I'm happy to offer.) But obviously you should do what feels most comfortable.
