The important thing is to leave the quotes and the references in place, to be unravelled and to be made sense of - and at the same time to make sure that the children know how to follow up the clues and solve the puzzles. That's easier now than it has ever been.

In the last resort education isn't about passing on information, it's about encouraging people to feel curious, and to discover that if they follow up on their curiosity they find out the answers, and find other wonderful things that they had no idea were there.

And the Mudcat provides splendid examples of how that works, day after day. And if you have to dig around sometimes to find them, that's OK too.
