This archive collects U.S. official documents concerning the national stance toward terrorism. Documents are sorted into several "volumes," which cover topics such as policy, the last war in Afghanistan, Nixon and the end of biowarfare programs, the reign of King Zahir (1970-1973), the 1979 Sverdlovsk anthrax controversy, the U.S. Special Force's search for bin Laden, U.S.-Taliban policy, and the air-ground transcripts of the planes lost during the 9/11 crisis.

Expect to find reports, memorandum, instructions, statements, transcripts, minutes, and more. The site and its content can be fairly dense, so it may be best to use the site to find one or two documents which are suitable for your classroom rather than having students explore it on their own.

DocsTeach, a National Archives and Records Administration project, recognizes the need to bring primary sources into your classroom. To assist in the effort, NARA has pulled together thousands of primary sources, as well as a selection of pre-made activities and tools for building your own primary-source-centric activities.

Documents offers exactly what it sounds like it would—primary sources. The sources are divided into chronological categories—Revolution and the New Nation, Expansion and Reform, Civil War and Reconstruction, Development of the Industrial United States, Emergence of Modern America, Great Depression and World War II, Postwar United States, and Contemporary United States. Results can then be narrowed further by selecting audio/visual, charts/graphics/data, image, map, or written document. If you prefer, you can use a keyword search. All search results are shown with thumbnails to give you a small preview of the sources for your consideration.

Activities provides pre-made classroom activities. These require access to a computer, and are based on the same tools which the site provides for making your own activities. You can also sort them by historical thinking skill—chronological thinking, comprehension, analysis and interpretation, research capabilities, and issues-analysis and decision-making. Registering gives you access to a much larger collection, many of which are created by other educators. There is no registration cost.

If you're registered, consider making your own activity for use by yourself and others. There are tools which help students to create sequences, participate in analytical discussion, connect documents, geographically map documents, use documents to gain an understanding of the bigger picture, weigh evidence, and examine source context.

Take a moment to peruse the Teacher Resources as well. Here, you can find information on national history standards, using DocsTeach activities in the classroom, Bloom's taxonomy, and the National Council of Social Studies.

The Central Intelligence Agency (CIA) has digitized thousands of formerly secret documents declassified to comply with Freedom of Information Act requests.

Keyword search capabilities are provided for the complete site. In addition, there are eight collections designated as "frequently requested records" that total nearly 8,000 documents. These collections cover a number of Cold War topics: CIA involvement in the 1954 coup in Guatemala; convicted spies Ethel and Julius Rosenberg; the 1961 Bay of Pigs affair; and two well-known espionage incidents.

Additional topics include POW MIAs in Vietnam, human rights abuses in Latin America, and UFOs. A disclaimer notes that some material cannot be disclosed due to national security laws, and released pages often have material deleted or blacked out. Still, the material offered is voluminous and useful for studying Cold War foreign policy and military history.

The New York Philharmonic Digital Archive contains materials dating back to 1842 and the original concert of New York Philharmonic, the oldest symphony orchestra in the U.S.

Sources available include business papers, images, programs, and scores. Other source types are in planning. Unfortunately, there's no easy way to browse the collection. You can either search for specific keywords, or leave the keyword box empty and select a source type—for example "Images." This will give you a list of all of the archive images to sift through. There are then menus on the left to help you pare the search down. However, the array of choices in the menus themselves is so extensive that patience is required to navigate the collection effectively.

That said, if you have anything specific that you are looking for, or you have time to explore, this website is potentially an invaluable source for music history. Scores may be the most use in the classroom, as they essentially give you an interactive (if you're willing to teach a song) form of period text.

Taking the Mystery out of Copyright provides a very brief introduction to copyright and the history of intellectual property. If you need anything beyond the very basics, unless you are interested in the major historical milestones leading to current copyright protection, this site probably will not meet your needs. However, if all you want to do is introduce the idea of copyright to very young students, you may find the site useful.

Visitors can select one of four sections. Copyright Exposed is a short animated video set to funk music which provides the basic idea that copyright "has got your back" when you produce a creative work. Files on Record provides a timeline of intellectual property history. Each milestone is accompanied by a primary source from the Library of Congress's collections. Here, you can read a few sentences on the Licensing Act of 1662 or the 1990 Architectural Works Copyright Protection Act. Reading the Fine Print offers two- to five-sentence answers on applications of copyright—protection of ideas, copyright on items you find, copyright on the Internet, when people can use your work without asking, the right to use a small sample of another work, and the reasons for registration. Steps to Copyright informs readers on how to register copyright (make something, fill out the form, pay the appropriate fee, and send nonreturnable copies).

This website presents historical sources and teaching materials that address notions of childhood and the experiences of children and youth throughout history and around the world. Primary sources can be found in a database of 200 annotated primary sources, including objects, photographs and paintings, quantitative evidence, and texts, as well as through 50 website reviews covering all regions of the world. More than 20 reviews and more than 70 primary sources relate to North American history.

The website also includes 20 teaching case studies written by experienced educators that model strategies for using primary sources to teach the history of childhood and youth, as well as 10 teaching modules that provide historical context, strategies for teaching with sets of roughly 10 primary sources, and a lesson plan and document-based question. These teaching resources cover topics ranging from the transatlantic slave trade, to girlhood as portrayed in the novel Little Women, to children and human rights. Eight case studies relate to North American history, as do two teaching modules.

The website also includes a useful introductory essay outlining major themes in the history of childhood and youth and addressing the use of primary sources for understanding this history.

One year after the sub-prime mortgage crisis, this website presents a small collection of historical materials and information surrounding four financial crises in the 19th and early 20th century: the Panic of 1837, the Panic of 1873, the Bankers' Panic of 1907, and the Great Crash of 1929. Each section includes a brief explanation of the crisis, including causes and consequences, and between four and six primary sources, including maps, images of bank notes, title deeds, and letters. These sources highlight the complexity of crises and their increasing internationalization over time, as well as issues surrounding historical interpretation of the crises.

The website also includes sections on the Waltham Watch Company, which drew on lessons learned during the Panic of 1937 to mechanize the production of watches; and the real-estate boom of the early 1920s, which has been used recently by economists and historians to better understand current connections between real estate markets and financial crisis. Finally, a bibliography of close to 30 works on the history of these crises, links to manuscript collections, trade publications, and financial databases, give website visitors suggestions for further study.

One of the Famous American Trials sites created by Douglas Linder of the University of Missouri, Kansas City, School of Law, this site explores the 1969-1970 trial of the Chicago Seven, a group of radicals accused of conspiring to incite a riot at the 1968 Democratic National Convention in Chicago. Linder provides a 1500-word account of the trial, which includes links to brief (100-word) explanations of specific terms and biographies of some of the key figures. The site provides a chronology of the lives of those involved in the trial from 1960 to 1998; images of two Yippie posters; a map of the key Chicago riot sites; and roughly 350-word biographies of 15 of the defendants, lawyers, and other figures in the trial. There are ten audio clips of defendants, prosecutors, and witnesses discussing various aspects of the riots and the trial. The site offers full-text versions of the indictment against the Chicago Seven, the trial manuscript, the contempt of court specifications against two of the defendants, and the appellate decision that overturned the contempt convictions and the convictions for intent to incite a riot. Additionally, there are 16 images of the riots and key figures and 14 quotations. A bibliography of 13 websites and 15 scholarly works leads to other sources for studying the Chicago Seven's trial and their lives as radical activists. This is an ideal site for researching 1960s activism and culture.

This site provides images and text about the 1906 San Francisco earthquake and fire. A timeline, from April 18 to April 23, covers major events and a facsimile of a roster lists names and addresses of those who died. There are 27 photographs of earthquake damage and 31 personal accounts, 1,200 to 8,000 words, that include Jack London's "Story of an Eyewitness." Among 67 transcriptions of articles from 1906 about the earthquake are 12 that discuss the relocation of Chinatown and the treatment of Chinese San Franscicans. There are 31 transcribed fire department reports, including an article about the reorganization of the department in the wake of the disaster, and a facsimile of the 1910 police report on the quake and fire. Army operations are discussed in 29 pieces of correspondence and navy evacuation operations are detailed in seven. In addition, a 700-word article describes the evacuation of the city by train. Engineering and scientific reports include 24 articles, letters, and reports about infrastructure issues, such as water supply and structural stability. A section about relief efforts includes a flier accusing the Red Cross of corruption and a resolution by a local plumbers union to volunteer their services. The site will be very useful for anyone interested in the earthquake and in urban and California history.
