Well known for its creation and adoption of modern Hebrew as its national language, Israel is still one of the most linguistically heterogeneous societies in the world. Bernard Spolsky and Elana Shohamy delve into this complex reality and describe a coherent picture of it, drawing from an updated model of linguistic policy which they elaborate. I found no few weaknesses in the book in regard to the sociological interpretation of sociolinguistic facts, but its major interest resides in the description of Israel's linguistic diversity and evolution. It is one of the very few attempts to date to do that, and it merits attention.
