Sdu

Sdu is a Dutch publishing company, whose name derives from the company's origin as the Staatsdrukkerij en -Uitgeverij, typically abbreviated as Staatsdrukkerij; the company started as the official publisher ("State Printing House") of Dutch governmental publications and of documents such as passports and voter registration cards. Along with the Staatscourant, it was the first Dutch company to receive the appellation "royal", awarded in 1806 by Louis-Napoléon Bonaparte.
