Laud’s book is one of the most affordable statistical mechanics texts. Used copies from Indian editions can be found on AbeBooks or eBay for $5–$15. If you absolutely need a PDF, consider purchasing a physical copy and then scanning it for personal use.
If you can find a legal PDF—through your library or a paid e-book store—use it as your ahead of qualifying exams (like the CSIR NET, GATE, or physics GRE). If you cannot, buy a cheap used copy; it will cost less than a pizza and serve you for decades.
