From Arch Daily:
The Royal Institute of British Architects (RIBA) have made 90,000 unique images from their visual archive available online. Architecture.com/images (also known as RIBApix) hosts the world’s largest collection of 16th century drawings by Palladio, as well as drawings by Sir Christopher Wren, Erno Goldfinger, Augustus Pugin, Denys Lasdun, and Edwin Lutyens.
As much architectural history as social documentation, the archives include extensive images of interior design, landscape, topography, construction and decorative arts. All beautifully captured by some of the world’s leading photographers including John Maltby, Edwin Smith, Henk Snoek, John Donat, Dell & Wainwright, Martin Charles and Tony Ray-Jones.
From the RIBApix Web Site:
All can be easily purchased or licensed through the RIBApix web shop. Lo-resolution Images can be downloaded for non-commercial private study or research.
