THE WORLD FACTBOOK
This online reference of the Central Intelligence Agency of the United States provides an incredible amount of information on countries: maps, geography, people, government, communications, transportation, military and transnational issues (eg, international disputes, refugees, trafficking in persons, illicit drugs, etc). The site is updated on a bi-weekly basis.

CHIEFS OF STATE AND CABINET MEMBERS OF FOREIGN GOVERNMENTS
Another online reference of the CIA, this provides listings, by government, of many of a country’s key players (PEPs) including the head of the central bank and ambassador to the US.

THE ASSOCIATION OF CERTIFIED ANTI-MONEY LAUNDERING SPECIALISTS
If you are considering a career in AML, this, in my opinion, is the organization to belong to and is still the gold standard for its CAMS certification. Much of the site is restricted to members.
Many more links coming soon. And feel free to suggest links of your own.
