Reading, searching and practicing online.

Short answers to the questions readers ask first.

How is the book organized?: Six parts and 23 chapters. Each chapter follows the same shape: opening problem, learning objectives, an annotated model, worked decisions, common mistakes, a compact reference, nine exercises, a takeaway, and a source note. The dashboard lists every part and chapter.
Where are the answers?: Under every exercise there is a Check your work button that reveals the explained answer in place. The complete answer key is also available chapter by chapter, with a return link to each exercise.
How does search work?: Press Ctrl + K (or /) anywhere in the book, or use the search box in the header. Results update as you type and can be filtered to chapters, exercises and answers, or reference material. Wrap a phrase in quotation marks for an exact match. The index is downloaded once and searched in your browser; the header search box sends nothing to a server. The full results page puts your query in the address bar so it can be bookmarked.
What are pins?: Pins save a page or section for quick reference: a chapter, an exercise, a glossary term, a table or a state. They appear on your dashboard and on the pins page, where you can reorder, export, import, or copy a share link. Pins are stored in this browser only, so export them before clearing site data or switching devices.
What does "Fictional training example — not legal authority" mean?: Some exercises and models use invented sources so the whole packet can be checked without a database. Every such source carries that label, rendered as a badge. Never cite a fictional source. Real examples carry a chapter source note describing exactly what was inspected.
Is this the same text as the print edition?: Yes. The site is generated from the same manuscript files that produce the print and PDF editions. Chapter and exercise identifiers (for example CC-04-05) are identical across editions. Page numbers are a print feature; online, use the section links and the subject index.
Light or dark?: Use the theme control in the header to choose light, dark, or follow your system.
Something looks wrong.: Source limits and open editorial questions are disclosed in each chapter's source note and in the scope statement. If you find an error in the text, use the report form; it records the exercise or section identifier and the edition for you. Corrections are logged on the updates page.
