This page on digital resources on lusophone African countries was curated by the Specialised Information Service (SIS) for Latin America, Caribbean and Latino Studies.
Here you will find a general overview as well as country-specific resources for Angola, Cape Verde, Guinea-Bissau, Mozambique, São Tomé and Príncipe as well as Equatorial Guinea. These countries are collectively known as PALOP (Países Africanos de Língua Oficial Portuguesa), Portuguese-speaking African countries.
The overview is in German but the links are for the most part self-explanatory and lead to Portuguese or English-language pages.
