History of Science and Technology 

A free online archive of hundreds of historical interviews with the 20th century's greatest physicists is now available from the Niels Bohr Library and Archives. It contains written transcripts and audio recordings of oral histories that date back 50 years.

The catalog contains 3,000+ hours of audio recordings from 1,500 physicists and astronomers. Some sound clips from the oral histories with the voices of the scientists themselves are also available.

The World Digital Library Project  makes available on the Internet significant primary materials from cultures around the world, including manuscripts, maps, rare books, musical scores, recordings, films, prints, photographs, archi­tectural drawings, and other significant cultural materials.

They are free and in many languages.

The objectives of the World Digital Library are to

• promote international and inter-cultural understanding and awareness
• provide resources to educators
• expand non-English and non-Western content on the Internet
• contribute to scholarly research
