Know what you are opening

External PDF opens a checked provider-hosted PDF. Read online opens an external text or resource; some providers require their own free account. Collection entries open a provider hub containing further resources. Publisher edition takes you to an edition you can obtain or borrow. OpenStax pages also offer PDF options through the provider.

Catalogue discovery entries offer subject-led reading prompts. They are not full-text reviews or confirmed age ratings; teachers and parents should preview their choices.

Use your teacher’s assigned edition for quotations and page references. Study level does not mean a text is on your examination specification.
