Turning The Pages showcases some of the oldest and most magnificient books in the British Library. You can virtually turn the pages on Leonardo Da Vinci’s notebooks, beautifully illustrated medieval texts, and the first atlas of Europe — among many others.
That’s neat in itself. What’s even better for English Language Learners is that each page in each book has a short text description with audio support. Much of the text would be accessible to high Intermediate English Language Learners.
I’ve placed the link on my World History page under The Later Middle Ages.
