Yes; it's definitely in Littlejohn's 2014 South West Climbs volume 2 - in the Exmoor Coast section [which actually strays into Somerset with Hurlstone Point]. It is, of course, a selected guide rather than definitive; it contains sixteen routes in the Valley of Rocks area of which eight are down on the underlying sea cliffs of The Yellow Stone and Wringcliff Bay - the latter generally occupying a higher grade range than that found on the landbound crags up above [Devil's Cheesewring, Castle Rock, etc].
