This is a sort of thesaurus question, I guess.
I'm thinking about the various kinds of books that have to do with illness/es or therapy. For some of them we have clear labels: to me, a "self-help" book, eg, would be something like "The Habits of Successful People" -- ie, there would be an element of the inspirational or exhortatory to a self-help book: this is how you pull your socks up.
But what do we call books that are somewhat more neutral than that? Say someone has developed an effective method of delivering a particular kind of therapy and simply wants to teach that method, straight up. Such a manual would not quite be a self-help book, yes/no?
And what about memoirs that are meant to be inspirational? Those can run the gamut from ultra-sentimental to very literary -- any terms that anyone associates with those, of any level?
This is really a more banal question than I've made it sound. My mind is just not producing many synonyms on this turf.
