This list is by no means an exhaustive list of everything that is out there in mathematics. It is intended to give the user a good place to start learning about the various fields in mathematics and the jobs available in each field. Newspapers from the many of the major eastern cities are also listed, in case one is interested in a specific region. Many additional sources are listed on each of the following web pages. Happy learning/hunting!
