In 1912, Japan presented Washington, DC, with 3,000 cherry trees as a gift. This Library of Congress exhibit uses primary sources to explore the history of the trees, the National Cherry Blossom Festival that grew up around them, and Japan/U.S. relations.

Primary sources are divided up by four themes. "Art and Documentation" includes three sources: a letter from Tokyo mayor Yei Theodora Ozaki to First Lady Helen Taft on the gift of the trees, a memo on artwork acquired by botanist Walter Tennyson Swingle in Japan, and a photograph of Swingle and Seisaku Funatsu, one of the group of Japanese experts who cultivated the trees gifted to the U.S.

In "A Special Gift to Washington from the City of Tokyo," visitors can view Swingle's collection of 11 Japanese watercolors depicting different types of cherry trees.

"Cherry Blossoms in Japanese Cultural History" collects 15 pieces of Japanese artwork depicting traditional hanami (flower viewing), as well as two pieces of Western artwork showing Japanese influence. Also included in this section are 12 stereographs of Japan during cherry blossom time, created between 1904 and 1908 for Western audiences.

"Enduring Symbols of Friendship" includes nine sources exploring the place of the cherry trees in Japan/U.S. relations. A 1938 Japanese magazine cover, notes for a 1934 speech by Japanese ambassador Hiroshi Satou, and a photo of children from the Japanese Embassy at the Tidal Basin show pre-World War II peace. Two political cartoons show how quickly the trees became a symbol of DC, and a photograph shows U.S. cherry blossom viewers during World War II. The section also features three photographs from a 2011 photography contest associated with the National Cherry Blossom Festival.

Visitors can also click on "Exhibition Items" to view all 55 primary sources, sortable alphabetically or by theme.

Some sources lack annotations, and existing annotations are sparse. However, this is a unique collection of sources that could be used as jumping-off points for exploring cultural exchange, international relations over time, and DC history.

The White House Historical Association works "to enhance the understanding, appreciation and enjoyment of the White House." The website has a number of useful educational resources if you know where to look.

Start with the Themes and Media page that gathers educational resources from the entire website into thematic categories from African American history to protests. Within each collection, you'll find relevant selections from the website's pool of 10 text timelines, more than 15 online exhibits and tours, and more than 20 lesson plans labeled by grade level. One exhibit covers the political symbolism of, and national reaction to, First Lady Lou Hoover's invitation of Jessie DePriest, wife of the first African American elected to Congress in the 20th century, to tea.

The History page gathers the majority of these resources in one location. From information on artwork in the White House to milestones in White House staff history to White House pets, there's plenty to discover.

Most of the content in the Classroom section overlaps with that in History. However, here you can access all available lesson plans, sorted by grade level (K–3, 4–8, 9–12), as well as more than 10 primary sources. Finally, this is the place to go for more information on touring the White House or reserving a program for your DC Metro-area classroom.

The Civilian Public Service Story answers the question, "Did individuals conscripted for World War II who were strongly opposed to killing have to fight?" The answer, something rarely discussed, is no. In the words of the site's introductory page, "Civilian Public Service (CPS) was a program developed at the onset of WWII which provided those whose conscience forbade them to kill, the opportunity to do work of national importance under civilian direction rather than go to war. Nearly 12,000 men made this choice, and many women voluntarily joined the cause. They fought forest fires, worked in mental institutions, planted trees, did dairy testing and served as subjects for medical experiments in more than 150 camps scattered throughout the United States."

The section "The Story Begins" consists of a brief summary of the history of conscientious objection in the U.S., beginning with colonial times. You can also find an annotated bibliography, listing approximately 18 works. Note that these works, and this site in its entirety, are intended for adult users. However, this does not preclude the information from being useful for K–12 history education.

"The People" consists of a few statistics on the World War II CPS population as well as a database of the men and women of the CPS, reproduced with permission from the Center of Conscience and War. These records, searchable and alphabetized by last name, may include year of birth, community, religious denomination, CPS entrance and exit dates, spouse, camps and units, higher education, and pre- and post-CPS occupation. These records may be of the most use in a classroom setting, as they could spark local history or oral history projects. "The Camps" provides a similar feature. Consider looking into CPS camps that were in your area using the map application on the site.
