This collection contains materials related to a full range of Blake's personal, professional, and academic lives. The bulk of the collection dates from the 1980s through the early 2000s. His professional and faculty papers document many of his interests, and primarily include published and unpublished lectures and articles. Although Blake delivered his lectures at various architectural schools in the United States and abroad, the specific locations of the lectures are not usually recorded on the documents. In addition, many articles he wrote for publication appear as annotated typescripts. There are also significant papers related to publication of his memoir No Place Like Utopia (Knopf, 1993), including correspondence and some production records. Throughout the professional and faculty papers are also found a large number of reference files relating to modern architecture, art, design, urbanism, technology, and current events, compiled over many decades. The collection also contains correspondence with personal friends, clients, and professional and academic colleagues. There is an especially significant amount of correspondence and clippings related to Patwant Singh, a Sikh writer, commentator, journalist, editor, and publisher, with whom Blake was a close friend.
