The Comptes rendus de l’Académie des Inscriptions et Belles-Lettres (CRAI) are now available on-line on the free portal Persée: http://www.persee.fr/web/
Thank to the search engine (by word, author or period), you can find the articles about Pompeii and follow some of it’s archaeological twists and turns since the second half of the XIXth century. These articles may have been published some time ago, yet they can be of great interest for the history of the excavations, their historical and scientific context and the relationships between French and Italian scholars.
Some of the results here.
You can also widen your research to all the scientific journals digitalized on Persée such as the Journal des Savants or the Mélanges de l’École française de Rome.
