Unsurprisingly, this was the record label of book publishers the Cambridge University Press. The records that it issued appear to have been tied-in with books that the firm published, and may in fact have been given away with them. At least one 7" appeared in the '70s, Brian Sargent's 'Troubadours and Minstrels', which dates from 1975 and had a catalogue number - an ISBN number? - of 0521204763.
