Of interest to the readers of this blog will be Le Journal de la Société des Américanistes.
More generally, there is a broad and excellent collection of journals at a portal named Persée. Full text articles are available from the older numbers. The collection includes major French-language periodicals in history, social sciences (including anthropology), and archaeology. Interesting journals for archaeologists include:
- Bulletin de la Société préhistorique française
- Bulletins et Mémoires de la Société d'Anthropologie de Paris
They also have a section with "Proceedings and Series" but I can seem to get the search engine to work there.
Otherwise, the site is attractive and functional.
