Books Custom Post Type (Genre, Authors and Series)

Books CPT registers a Book post type for managing books in WordPress. Taxonomies

• Genre — hierarchical categories for book genres
• Series — hierarchical categories for book series
• Authors — assign one or more authors per book

Book details Each book supports an excerpt, a series order field, and repeatable purchase links (retailer + URL). Add links in the Book details meta box below the editor. Book Purchase Links block Insert the Book Purchase Links block on a book page or template to show a single call-to-action button. Clicking it opens a dropdown of retailer links — so multiple stores never clutter the page with separate buttons. Find the block by searching book or buy, or browse the Books block category in the inserter. Customize the button text via Button label in the block settings sidebar when the block is selected. Preset retailers: Amazon, Apple Books, Barnes & Noble, Kobo, Google Play, Simple Digital Download (when that plugin is active), and Other (custom label). When Simple Digital Downloads is installed, choose Simple Digital Download as a retailer and pick a download. The purchase dropdown shows it as Buy Direct and sends buyers straight to Stripe checkout (or collects email for free downloads).
