This appendix provides a list of links referenced in the book, which are sorted chapter-wise.

Hyperlinks provide a gateway to the extensive literature that can be accessed on the Internet. They provide information above and beyond what one finds in a single article, book, blog, or other media formats. However, when one writes a book, the links provided in the printed book are useful to only those readers who would go to any lengths to find information. For others, these links are irksome, frustrating, and almost useless. They are, of course, useful in online formats, such as e-books.

This appendix is an attempt to provide guidance to the readers. However, some essential information is used in the book in some of the chapters; the links to those are mentioned in the upcoming sections.
