Toolbox Series: Online resources for African Studies.
We recommend the page on digital resources on lusophone African countries 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.
