Collingwood's ideas are still relevant. As a matter of fact, his perspective on historiography is that history belongs to the present, and we must see it through our time. He believes it is important to relate history through our own individual thought, which sort of better connects us with the past. Current historians often agree with Collingwood's rejection of propositional logic, but disagree with his rejection of "scientific history."
Reading Collingwood's autobiography, I came away with a favorite quote: "For the history of philosophy, as in every other kind, nothing capable of being learnt by heart, nothing capable of being memorized, is history."
