Men of muscle mystery

Maybelle Googly's lending a hand cataloguing a pile of non-fiction that's been bought on a visit for the Prison Library. [In case of confusion it needs to be said that no stock's been bought for the staff library since 1983.]

"How should I classify this?" she asks.

It's a coffee-table book of art studies of muscular men with oiled pecs and thighs like small emergent nations. We spend twenty minutes running through the schedules but we can't find a Dewey number for "gay porn."
