I have a first book in press with a publisher who has been absolutely great - I've felt hugely supported. They're not top-line in terms of prestige, though perfectly respectable.
For the second book, would you try for a better press (bearing in mind that would mean writing the whole of the second book before submission, so potentially quite a long period when I wouldn't have 'under contract' for that book on my CV)? Or would you try to stick with what you know? How do you think employers will see this one?
I'm postdoc without a permanent position, FWIW. I'm basically wondering whether or not having the second book under contract would be a stronger position than having the possibility it'd end up published somewhere better?
