Established in 1993, The Probert Encyclopaedia is one of the World Wide Web's longest running, largest and most celebrated independent encyclopaedias famed for its originality, reliability and integrity. Because we are independent we can be different. The Probert Encyclopaedia strives to provide accurate, reliable information to everyone. In March 2013 The Probert Encyclopaedia became part of the New Society for the Diffusion of Knowledge (NSDK), a not-for-profit independent, secular organisation providing free information to researchers through the World Wide Web. We supply text data, maps and images to museums, universities, film companies, documentary makers, schools, businesses and the general public. Funding comes from licensing high resolution maps and images, as well as public donations and advertising. We receive no government or corporate sponsorship. Researchers are welcome to copy any text and images they see on the web site. High-resolution versions of maps and images, where available, may be licensed. Details of how to license a high-resolution image or map may be found on the hosting web page.
