This is book on Linkers & Loaders by John R Lavine. The material included in the Text and Reference books are not sufficient to discuss the actual Linking and Loading schemes in UNIX/LINUX and Windows systems. This book is a authority to these topics. I’ll be discussing the case studies of Linking ( specially Dynamic Linking ) from this book.
