The Library has been supporting the legislation with one minor proviso: that in the case of orphan works, we can provide payment to rightsholders if and when they appear, rather than handing money over in advance to a governmental fund that will only rarely be used.
— Ben White at the British Library, writing for the New Statesman. Not a minor proviso, IMHO - an extended collective licensing regime that would have libraries paying up front to use works that are abandoned would be a massive waste. Much more reasonable for libraries to pay as appropriate on the very rare occasion that a rightsholder surfaces and demands compensation. (via arlpolicynotes)
