Here is a chapter-by-chapter breakdown of what you can expect from the updated version:

K.K. Tewari’s Electricity and Magnetism has stood the test of time because it respects the student’s journey from confusion to clarity. Whether you hold a physical copy, a legal e-book, or a library-issued PDF, what matters is the discipline to work through every example and problem. Start today—the laws of electromagnetism await.

Simply buy the physical book. It costs less than a pizza, and you get access to an author-sanctioned QR code that links to the official updated PDF.

If you meant something else by “develop complete feature” (e.g., a code to extract features from the PDF, a chapter-wise quiz, or a summarized notes document), please clarify and I’ll be happy to help with that instead.
