And just individual taste too, of course. Not her chosen genre. T.H. White, Tolkien, and Stewart are the only ones I remember her mentioning. Makes the White->Sutcliff–>Stewart line of influence re Lancelot rather sweet.

I think she visited in person some of the time: in one of the essays she throws shade at a place with a wheelchair ramp but no lift inside. Beyond that, I'm unclear on it too.

I'm surprised that the count of fantasy authors was so low. I would've thought that it was decently well-established as a pulp magazine genre, at least, by mid-century. (Then there's the "all fantasy is for children" issue too...)
