The self-described "largest online-database about worldwide architects and buildings" contains plans and images of buildings both built and potential and forms a record of the architecture of the 20th century. The database uses a search engine, which allows a particular project to be found by listing architect, location or key word.^[1] It has been described by the librarian of the Calouste Gulbenkian Foundation as "one of the most useful reference tools concerning architecture available on the internet."^[2]
