        "Open Free Books aims to be more than a learning resource: free textbooks for everyone worldwide, from elementary school through university — on the web, at no cost.",
        "We aim to cater to different syllabi and curricula across the globe. It is a community effort by educators and contributors around the world, built in the open on GitHub.",
        "Free means the whole book for everyone: read online without paywalls or premium unlocks. Open means anyone can fix a typo, add a chapter, or fork a book for a classroom."

        "Yes — free is the product, not a trial. Every book and chapter is readable without a subscription or premium unlock.",
        "Open Free Books offers no commercial services and no ads, now or in the future. Sustainability comes from community contribution and shared open infrastructure, not from turning learners into the product."

        "Open Free Books is non-commercial: no paywalls, no ad network, no investor-driven upsell. Books are static HTML in an open repository — readable in a browser today, forkable for your classroom tomorrow."

        "No. A great teacher still sets pace, asks hard questions, and notices when a student is stuck. That relationship is not what we are trying to automate.",
        "Textbooks are reference and structure: explanations, exercises, diagrams. Those can be free, forkable, and kept current on the web so teachers spend less time hunting permissions and more time teaching."

        "Paper and most \"digital\" textbooks are fixed layouts — hard to search, hard to update, and poor homes for live diagrams or interactives.",
        "HTML on the open web can link to sources, resize for any screen, embed simulations, and improve over time. The book becomes something you use, not a file you download once."

        "No. Chapters are authored HTML with care: figures, interactives, and maps where they help understanding — not bulk-generated slop or print PDFs pasted online.",

      "answer": [
        "Each subject in the catalog has a set of curricula you can filter by — exam boards, school programs, and similar labels — so you can see which chapters fit your syllabus. For Mathematics, the Compare tab documents how frameworks differ and how chapters map to them.",
        "We try to keep chapter structure and prerequisite maps compatible with as many curricula as possible. We do our best, but coverage is not perfect; the catalog will grow and improve as more people contribute.",
        "Those labels appear only in the catalog (badges and filters), not inside chapter pages. You choose what applies to you on the catalog; inside a chapter, the focus stays on the topic itself."
