A wider world of English reading
Follow a question across books.
Six interdisciplinary hubs connect public-domain classics, original contemporary guides and reading paths. Start with the subject that matters to you—not with a literary label.
How the hubs work
Past and present belong on the same reading map.
A classic text can show where an argument began; a contemporary book can show how the problem has changed. Linden keeps the source types clear while placing them in a useful conversation.
