Transnational historiography, as the word says, transcends the limits of locality, region, nation State and zooms in on the many and complex connections that are hidden by those classic boundaries, such as trade flows, migrations, exchange of ideas (religions) and techniques, and so on. Saunier offers an introduction that is full of examples, but at the same time is pervaded by a tough academic discourse, full of terminology of the social sciences. Thus often very difficult reading, worsened by the horrible layout (or the lack of it). But for those who want to know what this new loot in the "global turn" of historiography is, this is recommended reading. ( )
