Is the conjugation correct here?
I know "A family were there." can be grammatical when "A family" is being treated as a plural noun.
But the following example is different. The subject is plural but it's treated as singular. I've never encountered this pattern before.
It is no accident that Seamus Heaney’s selected poems is titled “Opened Ground,” since writing poems for this most remarkable farm boy was a kind of digging: “Between my finger and my thumb / The squat pen rests; snug as a gun.”
So what's going on here?
