Hi Kubur,
Just trying to make our research endeavours easier
Thanks to everyone !
I didn't expect the thread to catch on so quickly and I fear I don't have much to contribute myself after such great suggestions !
I do recommend the Quai Branly (of course), huge collection, but the photographic archives are maybe even more interesting !
The British museum one is also very good with some rare pieces, and is surprisingly not talked about a lot.
The SMB database contains some rare weapons from Cameroon which might be useful to people studying the area.
I will add this portal (German) :
https://kulturerbe.niedersachsen.de/start/
The Peabody Museum collections :

The American Museum of Natural History (very clear website with a lot of interesting pieces !) :
https://anthro.amnh.org/collections
The Welt Museum Wien :
https://www.weltmuseumwien.at/en/onlinecollection/
If I think of (or find) more I will add them !
