The TMI partial meltdown, which was the worst accident at an American commercial nuclear power plant, both altered nuclear regulation policies in the United States and shook the public's confidence in nuclear technology.

Echo has developed an online survey, which invites people to share their thoughts about the TMI crisis. We aim to collect entries from a broad spectrum of people, ranging from residents who lived near the plant to people who lived in a different part of the country (or in another country) and followed the events through the media. Our aim is to build a free and public archive that serves as a resource for activists and scholars alike.

These are the 18 artifact categories at The Bakken. Items can belong to more than one category. We have roughly 2500 artifacts. An electrostatic kit from the 18th century would be listed as a generator, a storage case, electrodes, a Leyden jar -- whatever was in the box the kit lived in. Here on the Web, we'll list things by their most noticeable attribute. You can learn a lot about a collection by studying the categories it is sorted into.

On July 20, 1969, at 10:56 pm (EDT), Neil Armstrong became the first person to walk on the moon.

Around the world, people stayed up late, woke up early, and stopped their work to watch their televisions or listen to their radios to witness this riveting milestone in the history of science and technology. Now, emblazoned in the popular consciousness, are Armstrong’s words: “That's one small step for a man, one giant leap for mankind.”

Please help us preserve the public memory of this historic event in an online archive so that future generations can understand the magnitude of this experience.

Since the invention of the wheel, mechanical innovation has critically influenced the development of civilization and industry as well as public welfare, safety and comfort. Through its History and Heritage program, ASME encourages public understanding of mechanical engineering, fosters the preservation of this heritage, and helps engineers become more involved in all aspects of history.

Help the American Red Cross Museum document the response to this historic event by sharing your September 11 experience with us. We're interested in everyone who participated directly in relief activities, donated blood, money and time to help those afflicted by the largest man-made disaster in our nation's history. We are also interested in accounts of local community-based efforts that were launched in response to the needs of the victims. How have these events changed your attitudes toward volunteering in times of local or national crises?

The Claude Shannon project seeks to preserve the memory of the man whose mathematical theories lay the groundwork for the digital communication technology underlying the Internet. Shannon’s ideas, initially applied to telephone switching systems and early computing, proved tremendously useful in other scientific fields including genetics, encryption, and quantum physics. Shannon, dubbed the father of modern information theory, also applied his theoretical work to one of his favorite hobbies, juggling. His famous juggling machines illustrated his creativity, inveterate tinkering and great powers of invention. If Shannon or his work has influenced you either professionally or personally, please contribute your experiences and recollections to Echo’s permanent digital archive.

The September 11 Digital Archive uses electronic media to collect, preserve, and present the history of the September 11, 2001 attacks in New York, Virginia, and Pennsylvania and the public responses to them. Funded by a major grant from the Alfred P. Sloan Foundation and organized by the American Social History Project at the City University of New York Graduate Center and the Center for History and New Media at George Mason University, the Digital Archive will contribute to the on-going effort by historians and archivists to record and preserve the record of 9/11 by: collecting first-hand accounts of the 9/11 attacks and the aftermath (especially voices currently under-represented on the web), collecting and archiving emails and digital images growing out of these events, organizing and annotating the most important web-based resources on the subject, and developing materials to contextualize and teach about the events. The Digital Archive will also use these events as a way of assessing how history is being recorded and preserved in the twenty-first century and as an opportunity to develop free software tools to help historians to do a better job of collecting, preserving, and writing history in the new century. Our goal is to create a permanent record of the events of September 11, 2001. In the process, we hope to foster some positive legacies of those terrible events by allowing people to tell their stories, making those stories available to a wide audience, providing historical context for understanding those events and their consequences, and helping historians and archivists improve their practices based on the lessons we learn from this project. The September 11 Digital Archive project formally ended in June, 2004, and although we continue to collect accounts submitted through the website, we are no longer updating the website.

"Where Were You When America Was Attacked?"
This site exists to gather the thoughts and emotions of everyday people to the events on and after September 11, 2001.

The Rosie the Riveter Memorial: Honoring American Women's Labor During WWII, is the first national monument to celebrate and interpret women's crucial contributions to the World War Two Home Front. It is located in Richmond, CA, in Rosie the Riveter Memorial Park at the site of the former Kaiser Shipyards, which were the largest and most productive of World War II.

The vision of Moving Here is to explore, record and illustrate why people came to England over the last 200 years, and what their experiences were and continue to be. The site mainly looks at the Caribbean, Irish, Jewish and South Asian communities but we are growing all the time!

This web site offers free access, for personal and educational use, to online versions of original material related to migration, including photographs, personal papers, government documents, maps and art objects, as well as a collection of sound recordings and video clips.
