Secondhand books weigh down the tables in the atmospheric covered alleyway between Oudezijds Achterburgwal and Kloveniersburgwal, where you'll rub tweed-patched elbows with University of Amsterdam professors thumbing through volumes of Marx, Aristotle et al. Old posters, maps and sheet music are for sale too. Most titles are in Dutch, though you'll find a few in English mixed in. Cash only.
