that covers fundamental and advanced topics in modern physics. While full PDF versions are generally protected by copyright, the book is available through major academic retailers like Key Content & Chapters

Atomic Physics Dr. S.N. Ghoshal is a widely recognized textbook published by S. Chand Publishing

While physical copies are widely available through retailers like Amazon and S. Chand Publishing, digital versions (PDFs) are often sought by students for their portability and annotation features. Academic libraries frequently provide digital access to the text for registered students. Atomic Physics

Physics hasn't changed. The derivation of the hydrogen fine structure is the same today as it was in 1975. Where Ghoshal fails is in modern quantum computing topics (quantum entanglement, Bell's inequalities) or recent Nobel prizes (attosecond physics). However, for classical atomic physics , it is bulletproof.
