On September 12, 2001, the American Folklife Center at the Library of Congress sent a notice to folklorists and ethnographers across the nation asking them to record on audiotape the thoughts and feelings expressed by individuals and communities following the terrorist attacks of September 11, 2001. The project was developed by Ann Hoog, who collaborated with American Folklife Center Director Peggy Bulger in the original call for participation. Materials were mailed to the Library of Congress beginning in September 2001. The collection reflects the regional, ethnic, socioeconomic, and political diversity of Americans at the time of the September 11 attacks.

The collection comprises 8980 items: 8100 manuscript materials; 386 sound recordings (SR); 421 graphic and photographic materials (GR and PH); 20 moving images (MV); 15 electronic media (CF); and 38 artifacts (AR). There are twelve boxes of manuscript materials divided into seven categories: Administrative Materials, Participant Documentation, Unpublished Writings, Reports, Published Works, Internet Folklore, Clippings and Online Articles. These include printout of e-mails, ephemera (from various internet web sites), posters, newspaper articles, personal essays, narratives, children's drawings, and other miscellaneous items that were left at the various memorials.

The Participant Documentation series is arranged in sub-folders (a paper folder within an archival folder) according to the participants' last names and the ID numbers of the materials which pertain to the documentation. This arrangement ensures that the interviewer and the interviewee, and the primary materials (sound recording, photographic images, etc.) are readily identifiable. In some cases, there is no documentation accompanying a specific sound recording, photograph, or other type of medium. Therefore, in some sub-folders there is a "?" after the SR number. This indicates that the documentation most likely goes with that SR number, but the name on the form has not been linked definitively with that particular sound recording. There is a folder entitled "Participant Documentation (Michigan)." Originally there were no tapes accompanying the forms from Michigan State University (MSU). A few irradiated tapes were found which were subsequently linked to Michigan State University (MSU), but could only be identified and not played because of the extensive damage done to the tapes by the irradiation process. The participant documentation is also divided into "originals" and "photocopies" (as there was no way to verify which items had been irradiated, all the documentation was photocopied). All photocopied materials can be served to readers.

There are twenty-two accounts of personal narratives and eleven poetic works within the Unpublished Writings subseries, and they are arranged chronologically. These accounts are the personal experiences of the writers on the day or days following September 11, 2001. Other accounts recall events in the authors' lives months after the attacks.

The Reports subseries consists of school projects that were submitted by several institutions such as Hunter College, Colorado College, and California State University. Each project was approached differently followed prescribed guidelines, which were to capture the thoughts and feelings expressed by the American people in the aftermath of September 11. For example, California State University presented its response in the form of a research project which incorporated the use of posters, overheads, cartoons, and newspaper clippings. The students at Colorado College, on the other hand, wrote term papers based on the interviews they conducted.

The Published Works subseries consists of written articles and statements referring to the events and reactions to the attacks of September 11. The works include excerpts from the , press releases, photographs, flyers, brochures, and other ephemera.

The Internet Folklore section is a compilation of Internet sites that comment on the events of September 11, through humor, images, memorials, legends, and Internet warnings.

The Clippings and Online Articles subseries includes most of the California State University at Chico reports, which contain a large number of newspaper clippings. These clippings are included here and cross-referenced with the reports.

Note that the manuscript materials include database printouts that capture information about sound recordings, graphic and photographic materials, moving images, electronic media, and artifacts, all of which are available on hard copy and on a zip disk located in Box 1, Folder 2.

The Sound Recordings series includes interviews with people who were in the World Trade Center and the Pentagon during the attacks, and also people living in East Sullivan, Maine; Des Moines, Iowa; Los Angeles, California, and many other towns and cities -- small and large -- across the country. Twenty-eight states are represented. The collection includes interviews with teachers and students from elementary to graduate school; police officers, firefighters and other emergency workers; secretaries, executives, librarians, city officials, and people whose families have lived in the United States for generations as well as those recently arrived.

There are approximately 200 interviews from New York City and Arlington, Virginia, but the majority of the interviews in the collection was gathered from other parts of the country. The content of the interviews include views on international relations, politics, economics, patriotism, charity efforts, fears of flying, prejudices, and how relationships were changed by the events of September 11, 2001.

The total number of sound recordings given in the Concordance is accurate as of 2005. Additional items may be added. All of the sound recordings have been duplicated.

The sound recordings database is available in the Folklife Reading Room organized by SR number and alphabetically by the interviewer's last name. The recordings are arranged alphabetically by state, institution of affiliation, interviewer's last name, and interviewee's last name. Using the "find" option in Access, researchers should be able to find a specific sound recording easily. A few sound recordings were added to the collection after the numbering arrangement was completed so the last recording, SR386, is not the final recording. The sound recordings were numbered consecutively regardless of format. Hence, the compact discs are not in sequence. Although the collection of audio recordings was the primary goal of this project, some people documented their community's reactions in photographs. Therefore, this collection also includes photographic documentation of some of the spontaneous memorial tributes created near the Pentagon, and in other parts of the country. These memorials, sign boards, and decorations all reflect the public discourse regarding the events. Candles and flowers, written messages and drawings from children, flags and other items, collectively express the grief and solidarity of individuals and businesses. The American Folklife Center (AFC) staff took photographs of memorials at Arlington Cemetery and near the Pentagon. The American Folklife Center (AFC) also received images from places such as Marietta, Georgia; Knoxville, Tennessee; and Las Vegas, Nevada. The digital graphic images are housed with the electronic media.

Moving Images are arranged alphabetically by state and institution of affiliation. The Moving Image series includes interviews and patriotic songs pertaining to September 11, 2001.

Artifacts are organized by format and institution of affiliation. The artifact collection consists of materials that were gathered from a temporary memorial site in Knoxville, Tennessee or collected as part of a project. They include flags, posters, copper signs, and a sample of the irradiated tapes.
