Arcam has a new (to me anyway) architectural map of Amsterdam online that you can browse and zoom. All part of the architectural guide which you can view as a timeline or search google style for architect, address or keyword in Amsterdam. Not bad, and perhaps a contributing factor to dutch architectures current strength. They really work all the media, news via the internet (see archined), books with nai & Architecture & Natura (one of my favourite bookshops, nay! shops anywhere), publishing architects of which rem is the best known of course & maybe with a cheerleader or two!
