Ethical tip: if you’re a piano teacher, buy a legal PDF or physical copy for each student. Reselling or sharing PDFs hurts the publishers who keep these classics in print.

If you search for "John W. Schaum Piano Course D The Orange Book" without the ".PDF.pdf" typo, you will have better luck finding official retailers.
